I have a configure.ac with the following just after AC_INIT
It works well.
<snip>
host=mips-elf
host_alias=mips-elf
ac_tool_prefix=mips-elf-
cross_compiling=yes
</snip>
This works fine, and when the AC_PROG_CC executes it looks exclusively
for 'mips-elf-gcc' and fails if not found. It also sets
'CC=mips-elf-gcc' in all my Makefiles.
This is for a source tree of embedded firmware code.

Hello,
is it possible to enforce cross-compilation by some configure arugments
or env vars?
I cross-compile for win32 using the mingw32 cross-compiler toolchain but
I *can* run the created excutables as I have wine installed. So
configure concludes I am not cross-compiling and this leads to various
problems later.
Of course, I can easily work around it by unregistering the binfmt
interpreter and thus losing the ability to run the MS executables
directly. But generally, the cross-compilation check does not seem to
be reliable so I would like to be able to ask for cross-compilation
explicitly.
