[PATCHv2] Revert "arm64: Use aarch64elf and aarch64elfb emulation mode variants"

[Laura Abbott]

Commit 38fc42486775 ("arm64: Use aarch64elf and aarch64elfb emulation mode
variants") unfortunately breaks with some toolchains:

  CHK     include/generated/compile.h
  LD [M]  arch/arm64/crypto/sha512-ce.o
aarch64-linux-gnu-ld: cannot open linker script file ldscripts/aarch64elf.xr: No such file or directory
make[1]: *** [scripts/Makefile.build:530: arch/arm64/crypto/sha512-ce.o] Error 1
make: *** [Makefile:1029: arch/arm64/crypto] Error 2

If the distribution doesn't package the associated linker strips from
binutils, this will fail. Both Fedora and Debian currently fall into
this category so just revert it.
