Hello,
I'm trying to build gcc-7.3.0 (md5 747d5010b7c6938b480bc6e4d7c4be9a of
tar.gz) natively on a MACHTYPE=mipsel-unknown-linux-gnu MIPS p5600 machine
under Debian Stretch. I'm getting an illegal instruction during libstdc++
build phase:

Makefile:523: recipe for target 'cow-dir.lo' failed
make[6]: *** [cow-dir.lo] Error 1
I have configured and launched the build as:
$ CPATH=/usr/include/mipsel-linux-gnu/
LIBRARY_PATH=/usr/lib/mipsel-linux-gnu/ $PWD/../gcc-7.3.0/configure
--enable-languages=c,c++ --with-float=hard --disable-multiarch
--target=mipsel-linux-gnu
$ CPATH=/usr/include/mipsel-linux-gnu
LIBRARY_PATH=/usr/lib/mipsel-linux-gnu make -j2
I've clearly misconfigured the build -- xgcc ended up with a wrong ISA, but
I can't figure out how. What am I missing?
Best regards,
Martin
