[PATCH] libgcc: Mark libgcc_s as executable to ensure its stripped

[Richard Purdie <richard.purdie@linuxfoundation.org>]

libgcc_s is not marked as executable and hence it doesn't get stripped. This
means its about 1MB larger than it needs to be. There is no good reason it
shouldn't get stripped so ensure it does and mark as executable.
