Comment(by dukeleto):
May I suggest that we cheat a little and use qemu attain the goal of what
we want from cross-compiling, without actually cross-compiling.
I stole this idea from how emacs is cross-compiled in OpenEmbedded. Here
is the rough idea:
1) We add some arguments to Configure.pl to specify a target architechture
2) Our config subsystem learns how to detect if qemu is available
3) If qemu isn't available, die if attempting to cross compile
4) If qemu is available, start a qemu process of the wanted target
architecture, then run the entire build process within qemu
The output of this will be binaries for architecture X, which are actually
compiled, through the magic unicorn farts of qemu,
for architecture Y.
I think that this is actually feasible in the short term, unlike
*actually* modifying our config+build system to natively
cross-compile, which I highly doubt will happen before the heat death of
the universe.
