Could you check the values of _alias in the top-level Makefile?
Alternately, could you edit ld/emulparams/elf32bmipn32-defs.sh and add
‘set’ just before the “unhandled emulation” line in order to see the
value of the variables?
I tried this on my x86_64 machine:
./configure -C --prefix=$HOME/soft --build=mips64el-unknown-linux-gnu
--target=mips64el-guix-linux-gnu
to mimic the configure flags shown at
<https://hydra.gnu.org/build/1470440/nixlog/4/raw>. Unfortunately it
doesn’t exhibit the problem.
Thanks for looking into it!
