When emerging perl-5.8.6-r5 with the CFLAGS march=pentium4, the build fails with "illegal instruction" errors during "make" stage. It looks like it's trying to build lib/Config.pm when it dies, but I'm not a developer and reading "make" results isn't my forte. Doing an "emerge" with CFLAGS march=i686 works fine. Reproducible: Always Steps to Reproduce: 1. USE="minimal" CFLAGS="-O2 -march=pentium4 -fomit-frame-pointer" emerge perl 2. 3.

Mass re-assign.
Actually, this was a mistake. I realized that I was compiling on the wrong computer (remotely of course). That one was a Pentium II. Doh!
