[Toybox] Can not cross compile on Mac OS X (Mavericks)

[Raphael Cohn]

Originally raised as GitHub issue #17



   - make menuconfig works
   - make fails because a sed expression isn't understood by Mac OS X (and
   hence BSD) sed It may be possible to have a different expression. If you
   can give me a little insight into what the expression is trying to do, I
   can have a go at sorting this out.

I'm really keen to get a minimal toybox working on other POSIX platforms,
because it provides an excellent baseline for a consistent, secure and
sensible set of tools to enable cross compilation toolchains. Oh, and not
using autocruft gets it an extra star...
