make extensions failing on OS X

[sleepdeprecation]

Running make extensions is failing for me on OS X.

I'm not sure what the issue is. Running make extensions outputs:

cd fancy-backtrace && /Applications/Xcode.app/Contents/Developer/usr/bin/make

This is Homebrew's fault. binutils 2.24 no longer ships with libiberty any more, which is odd...

I've contributed to a few homebrew formulas, I'm interested in why that's
happening.

If someone can get a full-featured "fancy backtrace" implementation that
doesn't rely on libiberty, be my guest.. I remember spending a few weeks
tinkering with this code and making it cross-platform.

Apparently the libiberty folks want every program that relies on it to distribute their own copy. That's why Homebrew pulled it. Go figure.

I remember making almost that exact comment somewhere else - but anyway, @sduensin, you're right. We should probably vendor it somewhere, if someone want to submit a pull request for that, be my guest :)
