math/gsl: Repair math/gsl build to support ARMv6

[sbruno]

Summary

This port uses x86 specific ASM to generate floating point function support. DTRT for ARMv6

[sbruno]

hold on reviewing, I'll update in a bit. there might be a way to support this.

[sbruno]

Actually, Nathan recognized the build failure and pointed me at the same spot
that was used to repair PPC to repair the ARM build failure. Amusing.

How about changing the error string as well?

There are a bunch of mentions to powerpc in the error strings.

Again here.

[sbruno]

Update error strings to be more generic instead of powerpc specific

[nwhitehorn]

Should we have #if !defined(i386) && !defined(amd64) instead of whitelisting powerpc and arm? The stuff not being included is very x87 specific. Or use the gnuc99 fenv support, which looks like it's MI?

[sbruno]

Even more better version from nathan.

Drop patch-ieee-utils-fp-freebsd.c alltogether and change the order
of #ifdefs in the setup to pull in fp-gnuc99.c instead of fp-freebsd.cc

[sbruno]

needs a redports shake I think. It built here for 11-current amd64 locally.

[nwhitehorn]

I like the approach. It builds and works on powerpc64 11. It probably does need a test, but otherwise it looks good from my end.

[sbruno]

Bump port revision.

Looks good. Thanks!
