Add workaround from gdbserver's gdb_proc_service.h to GDB
This commit adds a workaround from gdbserver's gdb_proc_service.h to GDB's. It doesn't seem to have been needed on any glibc as far back as 2001, but it's possibly required for other C libraries so I've retained it. gdb/ChangeLog: * configure.ac: Check if sys/procfs.h defines elf_fpregset_t. (AC_CHECK_HEADERS): Check for linux/elf.h. * configure, config.in: Rebuild. * gdb_proc_service.h: Include linux/elf.h if sys/procfs.h doesn't define elf_fpregset_t.
