Fix GDB build fail on Aarch64 when -fno-common is enabled
Current trunk GDB (and gdb-7.8.1 too) fails to build on Aarch64 when
-fno-common is enabled. It fails during link stage due to multiple
definition of `tdesc_aarch64':

This happens because struct target_desc *tdesc_aarch64 is defined in
gdb/features/aarch64.c, which is included by two files
(gdb/aarch64-linux-nat.c and gdb/aarch64-tdep.c).
