Here we are! :-)
So far I’ve only tested with “simple” cases, namely GMP/MPFR/MPC, and it
all cross-builds correctly for mips64el-linux-gnu (N32). I’ve changed
hydra.scm so that Hydra cross-builds a few packages for us. Probably
package definitions and perhaps build systems will need to be adjusted
to allow cross-compilation of more packages, but the foundations are in
place.
Comments and bug reports welcome!
