Unable to build FreeBSD xdev tools for ARM on FreeBSD 10.0-CURRENT

[Tim Kientzle]

I looked at this very briefly a while back.  It looks like a great
opportunity for someone interested in learning more about
toolchain and library issues.

Related:  There's an active discussion on current@ about
switching FreeBSD's default compiler to clang.  Resolving
these issues would be a big help in that effort.

Cheers,

Tim
