Sorry, I pressed the wrong button on my email client... silly me. I also
might have not understood your question then...
Its build system tests whether the compiler works, and it does that by
building a dummy binary. However, the binary fails to link as the linker
can't find libmachuser and libhurduser, which are provided by libc,
without --rpath. (If this is what you were asking about)
