gdb: pass gdb_cv_prfpregset_t_broken=no
Starting with glibc 2.25, the proc_service.h header has been copied from gdb to glibc so other tools can use it. However, that makes it necessary to make sure that declaration of prfpregset_t declaration is consistent between gdb and glibc. In gdb, however, there is a workaround for a broken prfpregset_t declaration in glibc 2.3 which uses AC_TRY_RUN to detect if it's needed, which doesn't work in cross-compilation. So pass the cache option to configure. It needs to be passed to GDB_CONF_ENV to build gdbserver only but also to GDB_MAKE_ENV, because otherwise it does not get passed to the configure script of nested packages while building gdbserver with full debugger.
