Is there a demand for this configuration?  In that case, we should
have something more fine-grained that inhibit_libc, which suppresses
the profiling support along with eprintf.

It's also more convenient that writing all the binaries by hand.  But
still moe convenient is just to use a unified source tree and build
everything in one go.

Why would you want to build the libraries on a different machine than
the compiler?
