aarch64: Improve conditional compilation

With -Wundef one could get warnings of undefined symbols.
This patch tries to fix this issue.

Furthermore, the case where there is BTI but no Pointer Authentication
now uses GNU_PROPERTY_AARCH64_BTI in the check which should correctly
reflect that feature's enabled state.
