Fix PR16543

Tests in gdb.gdb fail because directory gdb/testsuite/gdb.gdb doesn't
exist in build tree.  This patch appends gdb.gdb/Makefile in AC_OUTPUT,
and adds new Makefile.in in gdb.gdb, so that directory gdb.gdb can be
created during configure.

With this patch applied, tests under gdb.gdb can be run,

$ make check RUNTESTFLAGS='--directory=gdb.gdb'

Using /usr/share/dejagnu/config/unix.exp as generic interface file for target.
