gdb's AC_LIB_HAVE_LINKFLAGS macro hardcodes a search starting with /usr/lib/ which can lead to libgmp from the wrong architecture with the result that the test fails. Even if a libgmp is found there it is now the one that should be used. This is the same macro used for expat and lzma for which there are already specific CONF_OPTS flags added here. Add the same flag for libgmp and move the handling down so that it is logically grouped with the other similar options. Note that there is no --with(out)-gmp flag to configure, as the dependency is mandatory, so only the --with-libgmp-prefix option is specified.
