What I meant to say here, is that via a couple of knobs akin to
‘current-target-endianness’, you could actually cross-build for any
target.
This is different from Binutils/GCC: a cross-GCC can only cross-build
for the target that was specified when that cross-GCC was built.
Conversely, a single Guile instance could compile code for any target.
Thus ‘%target-type’ would be inappropriate IMO because the target could
be chosen at run-time and it could be anything.
Does that make sense?
Besides, the UI could be made familiar. For instance
‘guile-tools compile --target=TRIPLET’ would be fine with me.

Ooh, cool! :-)

The prefix is added automatically for cross-Binutils and cross-GCC,
hence this example.
Thanks,
