Not within the framework of sourcemage, no. I have been playing with this
for a bit, and came to the conclusion that it would be possible, as long as
the installroot is always set and used. To make a cross-compiler, all you
need to do is

./configure --host=$THE_COMPUTER_YOU_ARE_BUILDING_ON           \
            --build=$THE_COMPUTER_IT_WILL_EVENTUALLY_RUN_ON    \
            --target=$THE_COMPUTER_IT_WILL_GENERATE_CODE_FOR

So, for a x86-cross-mips, its

./configure --host=i386-pc-linux-gnu \
            --build=i386-pc-linux-gnu \
            --target=mips-linux-gnu

Or something like that. Have the binutils source in your gcc source
directory to build that at the same time with the same options. After this
is installed, you can cross-compile stuff by setting "--build=mips" in
configure, or by exporting CC=mips-pc-linux-gnu-gcc.

I think it would be great for sorcery to support cross-compiles, as it would
allow you to set up a compile farm serving binaries for any machine you
have. Which would be very nice. It would, however, require some hacking of
almost every spell to install in the right place :o( . Unless anyone can
think of another way to do it.
