[PATCH AUTOSEL 6.11 107/244] tools/nolibc: powerpc: limit stack-protector workaround to GCC

[Sasha Levin <sashal@kernel.org>]

From: Thomas Weißschuh <linux@weissschuh.net>

[ Upstream commit 1daea158d0aae0770371f3079305a29fdb66829e ]

As mentioned in the comment, the workaround for
__attribute__((no_stack_protector)) is only necessary on GCC.
Avoid applying the workaround on clang, as clang does not recognize
__attribute__((__optimize__)) and would fail.
