Remove ancient workaround
This commit removes a workaround for a bug in glibc 2.1.3, which was released 2000-02-24 and superseded 2000-11-09. gdb/ChangeLog: * gdb_proc_service.h (gdb_prfpregset_t): Remove typedef. * proc-service.c (ps_lgetfpregs, ps_lsetfpregs): Use prfpregset_t instead of gdb_prfpregset_t. * configure.ac (PRFPREGSET_T_BROKEN): Remove check. * configure, config.in: Rebuild.
