The !defined(__ANDROID__) is redundant. Android is never glibc.

I missed this the other day. I think this change isn't needed because we can (I think) just not include <execinfo.h> now. It was added to support Host::Backtrace using backtrace, but that code has changed and is no longer here.

I tested it and it compiles fine without execinfo.h (Mint distro). Should I go on and remove the header? I'll keep an eye on the buildbots just in case.

I think so. A removal sounds so much better than having an #ifdef. :)
