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.

Build with fallback can be enabled by passing the `configure` command
line argument `--disable-smp-require-native-atomics`

LM_TRY_ENABLE_CFLAG takes which environment variable should be updated
but only CFLAGS was updated. Though CFLAGS is the normally the intended

- Teach lib/erl_interface/configure.in to look for
pthreads support in libc (where it can be found on QNX)
- A minor tweak such that this configure *fails* if you pass --enable-threads and
no pthreads support can be found.

The previous iteration didn't work for big-endian systems. Now use
code very close to what Erts does internally.
Also, only warn when the double endianness is unknown - i.e. when
we're cross-compiling.

On some ARMs (and maybe other platforms), doubles are stored with the

architectures.
The symptom is this:

Detect that and account for it when decoding floats.
