Apparently glibc is dropping libieee.a in the next release. In Fedora
Rawhide, -mieee-fp on i686 results in:
/usr/bin/ld: Cannot find -lieee
Dropping -mieee-fp from csiro.cmake fixes it for me. Also works with glibc
2.25. Not sure about older ones.

Fedora doesn't build for alpha, so no idea there.
