The issue here appears to be that libiberty configure script probes
for and finds an appropriate AR for the --build/--target combination.
However, the gdbserver configure does not probe for AR but does
override the AR used in the libiberty build by explicitly passing AR
to the sub-builds.  This has the effect of passing the systems 'ar'
rather than an ar appropriate for the --build/--target combination.

An alternative  approach to that suggested by James is to have the
gdbserver configure scri[t probe for AR to ensure that something sane
is passed on to the sub-builds.

Patch attached.

OK ?
