Laura Abbott 9caee771b5 Fix for arm64 compilation issue
The short answer is that it looks like Fedora binutils doesn't quite
work with this patch. The long answer might be more complicated but this
gets things compiling.

This reverts commit 38fc4248677552ce35efc09902fdcb06b61d7ef9.
This breaks compilation with Fedora gcc-8 tool chains:
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
Fixes: 38fc42486775 ("arm64: Use aarch64elf and aarch64elfb emulation mode variants")

A bit rushed and I'm still debugging but I wanted to send this out
before anyone else gets hit since it is -rc4. Seeing this on both native
and cross compiles.
