This patch allows examination of the registers FS_BASE and GS_BASE for Linux Systems running on 64bit. Tests for simple read and write of the new registers is also added with this patch. 2017-01-27 Walfred Tedeschi <walfred.tedeschi@intel.com> Richard Henderson <rth@redhat.com> gdb/ChangeLog: * amd64-linux-nat.c (PTRACE_ARCH_PRCTL): New define.
