x86: Error on -fcf-protection with incompatible target
GCC issues an error on -fcf-protection with incompatible target:
... -fcf-protection ... libstdc++-v3/testsuite/29_atomics/atomic_flag/test_and_set/explicit-hle.cc -m32 -O2 -g0 -fno-exceptions -fno-asynchronous-unwind-tables -march=i486 ...
cc1plus: error: '-fcf-protection' is not compatible with this target
FAIL: 29_atomics/atomic_flag/test_and_set/explicit-hle.cc (test for excess errors)
Add -fcf-protection=none to -march=i486 to compile explicit-hle.cc.
* testsuite/29_atomics/atomic_flag/test_and_set/explicit-hle.cc:
Add -fcf-protection=none to -march=i486.
