gcc: enable branch protection by standard
Pass --enable-standard-branch-protection. This is an aarch64-specific
option (currently) which does nothing on other targets. On aarch64 this
generates code uses BTI/PAC instructions to mitigate Return Orientated
Programming attacks. This approach is backwards compatible and the code
size/performance impact is typically negliable.
