gcc: Do not set -march for arm64 for libatomic

libatomic has mind of its own when it comes to setting -march for arm64
which conflicts with -mcpu option we pass from environment in some cases
since we always pass -march/-mcpu in OE, its safe to remove this option

mcpu removal from cortex-a55 is no longer needed since the option
conflict is now removed from libatomic instead

(From OE-Core rev: a5331c5a8bbe63c6c2e56ebec496b28968d4663d)
