Re: Enforcing cross-compilation

[Robert Woodworth]

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.
