There’s already ‘%host-type’.  However, I don’t think defining
‘%target-type’ would make sense since:

  1. Of the GNU triplet, only the $target_arch matters for bytecode;

  2. You can really choose at run-time what target you want to build
     for, by just setting the endianness fluid.

Now, if we want to produce something comparable to cross-GCC &
cross-Binutils[*], we could install, say, arm-linux-gnueabi-guile-tools
in addition to guile-tools; the former would somehow set the right
endianness for that target when running ‘arm-linux-gnueabi-guile-tools
compile’.

WDYT?

Thanks,
