[FYI] Fix gdb build on macOS

[FYI] Fix gdb build on macOS

[Tom Tromey]

Internal testing showed that the macOS port did not build.  The
breakage was caused by the patch to remove the gdbarch.h include from
defs.h.  This patch fixes the problem.

[gdb] Fix gdb build on mips64-linux

When compiling for mips64-linux, we get:
...
src/gdb/linux-nat-trad.c:139:12: error: ‘gdbarch_num_regs’ was not declared \
  in this scope
  139 |   regnum < gdbarch_num_regs (regcache->arch ());
...

Fix this by including gdbarch.h in linux-nat-trad.c, similar to commit
b1c896b365 "Fix gdb build on macOS".

Build on mips64-linux.
