ARM and AArch64 are separate toolchain ports requiring separate compilers.
There is no support for multilib headers supporting both in the same
header. (Debian/Ubuntu multiarch configurations put all bits/ and sys/
headers in multiarch directory arrangements so could handle having both
versions of a sys/ header installed without problems.)
