Reland "[AArch64] handle -Wa,-march="

This reverts commit fd11a26d368c5a909fb88548fef2cee7a6c2c931, which was
reverted by 9145a3d4ab7eb05d9fb113b5392e8961df629b88 due to a test
failure on aarch64 backend, e.g.
https://lab.llvm.org/buildbot/#/builders/43/builds/7031. This patch
fixed the test failure.
