driver: Also prune joined switches with negation
When -march=native is passed to host_detect_local_cpu to the backend,
it overrides all command lines after it. That means
$ gcc -march=native -march=armv8-a
is treated as
$ gcc -march=armv8-a -march=native
Prune joined switches with Negative and RejectNegative to allow
-march=armv8-a to override previous -march=native on command-line.
This is the same fix as was applied for i386 in SVN revision 269164 but for
aarch64 and arm.

(mtune=): Add Negative(mtune=).
(mcpu=): Add Negative(mcpu=).
