* msp/double_middle_endian/OTP-10209:
Configure now assumed normal doubles
Revise the autoconf tests for double middle endianness.
Add test for floating-point output to float_SUITE.
Unbreak floating point on middle-endian machines.

On some ARMs (and maybe other platforms), doubles are stored with the
the two 32-bit words reversed with respect to more common
architectures.
The symptom is this:
> io_lib:write(1.0).

Detect that and account for it when decoding floats.

With Atmel's recent buildroot-v3.0.0 release for AVR32, some changes
were needed in order to properly cross compile Erlang/OTP for the
platform.
Tested with R14B04 on a mk I NGW100.

improvements.
Most notable:
Lots of cross compilation improvements. The old cross compilation
support was more or less non-existing as well as broken. Please,
note that the cross compilation support should still be
considered as experimental. Also note that old cross compilation
configurations cannot be used without modifications. For more
information on cross compiling Erlang/OTP see the
$ERL_TOP/INSTALL-CROSS.md file.
Support for staged install using <url
href="http://www.gnu.org/prep/standards/html_node/DESTDIR.html">D
ESTDIR</url>. The old broken INSTALL_PREFIX has also been fixed.
For more information see the $ERL_TOP/INSTALL.md file.
Documentation of the release target of the top Makefile. For more
information see the $ERL_TOP/INSTALL.md file.
make install now by default creates relative symbolic links
instead of absolute ones. For more information see the
$ERL_TOP/INSTALL.md file.
$ERL_TOP/configure --help=recursive now works and prints help for
all applications with configure scripts.
Doing make install, or make release directly after make all no
longer triggers miscellaneous rebuilds.
Existing bootstrap system is now used when doing make install, or
make release without a preceding make all.
The crypto and ssl applications use the same runtime library path
when dynamically linking against libssl.so and libcrypto.so. The
runtime library search path has also been extended.
The configure scripts of erl_interface and odbc now search for
thread libraries and thread library quirks the same way as erts
do.
The configure script of the odbc application now also looks for
odbc libraries in lib64 and lib/64 directories when building on a
64-bit system.
The config.h.in file in the erl_interface application is now
automatically generated in instead of statically updated which
reduces the risk of configure tests without any effect.
(Thanks to Henrik Riomar for suggestions and testing)

Implemented erl-xcomp-avr32-atmel-linux-gnu.conf to support cross compilation
of Erlang on Atmel's AVR32-Linux: http://www.atmel.no/buildroot/
Built using a Ubuntu 9.10 host, with buildroot-2.3.0 and tested on on Atmel's
NGW100 development board.
