Do not link asan_rtl_x86_64.S for non x86_64 platforms.
Do not link asan_rtl_x86_64.S for non x86_64 platforms.
Prior to this CL asan_rtl_x86_64.S would be always be linked when
building compiler-rt for non x86_64 platforms, this normally isn't an
issue since at that link time is an empty file anyway.
When attempting to link a Aarch64 program with branch protection enabled
with the address sanitizer.
E.g.
```
clang --target=aarch64 \
-fsanitize=address \
-mbranch-protection=standard \
-Wl,-z,force-bti
-o test \
test.cc
```
Results in the linking error from the sections generated from the empty
asan_rtl_x86_64.S owed to missing a .note.gnu.property
