remove strerror module

This fixes the mingw build breakage reported by Pierre.

I found that the gnulib strerror module somehow requires us to pull in
the gethostname module.  However, pulling in the gethostname module
makes many things break.

I've sent a bug report to gnulib.

Meanwhile, removing the strerror module should not harm gdb and fixes
the build.

I'm checking this in.
