Hmm... This patch is about not repeating -mstrict-align twice, which is
a bug unrelated with switching to -mno-unaligned-access.

Besides, -mstrict-align means "Don't assume that unaligned accesses are
handled", which I think is for aarch64 what -mno-unaligned-access is
for arm(32), so it *should* be specified.

Amicalement,
