sstrip needs a ELF-based host machine (as Khem pointed), as it runs on
the host, not on the target.

It is not the target headers that are needed, but the host ones.
sstrip will not be compiled against anything from the sysroot.

Or maybe MacOS-X is not an ELF host, and lacks those headers? ;-)

Just disable sstrip, it's not really needed most of the time (and is broken
on a few archs, eg. PPC). I'm thinking about just removing it in the next
