Added support for ENEA OSE

This port has support for both non-smp and smp.

It contains a new way to do io checking in which erts_poll_wait
receives the payload of the polled entity. This has implications
for all linked-in drivers.

+## -----------------------------------------------------------------------------
+
+## Note that you cannot define arbitrary variables in a cross compilation

+#   `--build=$erl_xcomp_build' argument to the `configure' script. It does
+#   not have to be a full `CPU-VENDOR-OS' triplet, but can be. The full

+## -- Optional Feature, and Bug Tests ------------------------------------------
+
+## These tests cannot (always) be done automatically when cross compiling. You
+## usually do not need to set these variables. Only set these if you really
+## know what you are doing.
+
+## Note that some of these values will override results of tests performed
+## by `configure', and some will not be used until `configure' is sure that
+## it cannot figure the result out.
+
+## The `configure' script will issue a warning when a default value is used.
+## When a variable has been set, no warning will be issued.
+
+# * `erl_xcomp_after_morecore_hook' - `yes|no'. Defaults to `no'. If `yes',
+#   the target system must have a working `__after_morecore_hook' that can be
+#   used for tracking used `malloc()' implementations core memory usage.
+#   This is currently only used by unsupported features.
+#erl_xcomp_after_morecore_hook=
+
+# * `erl_xcomp_bigendian' - `yes|no'. No default. If `yes', the target system
+#   must be big endian. If `no', little endian. This can often be
+#   automatically detected, but not always. If not automatically detected,
+#   `configure' will fail unless this variable is set. Since no default
+#   value is used, `configure' will try to figure this out automatically.
+#erl_xcomp_bigendian=
+
+# * `erl_xcomp_double_middle` - `yes|no`. No default. If `yes`, the
+#   target system must have doubles in "middle-endian" format. If
+#   `no`, it has "regular" endianness. This can often be automatically
+#   detected, but not always. If not automatically detected,
+#   `configure` will fail unless this variable is set. Since no
+#   default value is used, `configure` will try to figure this out
+#   automatically.
+#erl_xcomp_double_middle_endian
+
+# * `erl_xcomp_clock_gettime_cpu_time' - `yes|no'. Defaults to `no'. If `yes',

+#   that can be used for retrieving process CPU time.
+#erl_xcomp_clock_gettime_cpu_time=
+
+# * `erl_xcomp_getaddrinfo' - `yes|no'. Defaults to `no'. If `yes', the target

+#   handle both IPv4 and IPv6.
+#erl_xcomp_getaddrinfo=
+
+# * `erl_xcomp_gethrvtime_procfs_ioctl' - `yes|no'. Defaults to `no'. If `yes',

+#   is used with procfs `ioctl()'.
+#erl_xcomp_gethrvtime_procfs_ioctl=
+
+# * `erl_xcomp_dlsym_brk_wrappers' - `yes|no'. Defaults to `no'. If `yes', the
+#   target system must have a working `dlsym(RTLD_NEXT, <S>)' implementation
+#   that can be used on `brk' and `sbrk' symbols used by the `malloc()'
+#   implementation in use, and by this track the `malloc()' implementations
+#   core memory usage. This is currently only used by unsupported features.
+#erl_xcomp_dlsym_brk_wrappers=
+
+# * `erl_xcomp_kqueue' - `yes|no'. Defaults to `no'. If `yes', the target
+#   system must have a working `kqueue()' implementation that returns a file
+#   descriptor which can be used by `poll()' and/or `select()'. If `no' and
+#   the target system has not got `epoll()' or `/dev/poll', the kernel-poll
+#   feature will be disabled.
+#erl_xcomp_kqueue=
+
+# * `erl_xcomp_linux_clock_gettime_correction' - `yes|no'. Defaults to `yes' on
+#   Linux; otherwise, `no'. If `yes', `clock_gettime(CLOCK_MONOTONIC, _)' on
+#   the target system must work. This variable is recommended to be set to
+#   `no' on Linux systems with kernel versions less than 2.6.
+#erl_xcomp_linux_clock_gettime_correction=
+
+# * `erl_xcomp_linux_nptl' - `yes|no'. Defaults to `yes' on Linux; otherwise,
+#   `no'. If `yes', the target system must have NPTL (Native POSIX Thread
+#   Library). Older Linux systems have LinuxThreads instead of NPTL (Linux
+#   kernel versions typically less than 2.6).
+#erl_xcomp_linux_nptl=
+
+# * `erl_xcomp_linux_usable_sigaltstack' - `yes|no'. Defaults to `yes' on Linux;
+#   otherwise, `no'. If `yes', `sigaltstack()' must be usable on the target
+#   system. `sigaltstack()' on Linux kernel versions less than 2.4 are
+#   broken.
+#erl_xcomp_linux_usable_sigaltstack=
+
+# * `erl_xcomp_linux_usable_sigusrx' - `yes|no'. Defaults to `yes'. If `yes',
+#   the `SIGUSR1' and `SIGUSR2' signals must be usable by the ERTS. Old
+#   LinuxThreads thread libraries (Linux kernel versions typically less than
+#   2.2) used these signals and made them unusable by the ERTS.
+#erl_xcomp_linux_usable_sigusrx=
+
+# * `erl_xcomp_poll' - `yes|no'. Defaults to `no' on Darwin/MacOSX; otherwise,
+#   `yes'. If `yes', the target system must have a working `poll()'

+#   used instead of `poll()'.
+erl_xcomp_poll=no
+
+# * `erl_xcomp_putenv_copy' - `yes|no'. Defaults to `no'. If `yes', the target

+#   key/value pair.
+#erl_xcomp_putenv_copy=
