[Plplot-devel] libieee.a is no more

[Orion P. <or...@nw...>]

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.
