Subject: [PATCH] arm: Check for __ELF__ instead of !__APPLE__, for using
For windows, when building with armasm, we already filtered these out
with gas-preprocessor.
By filtering them out already in the source, we can also build directly
with clang for windows (which also require wrapping the assembler in
gas-preprocessor for converting instructions to thumb form, but
gas-preprocessor doesn't and shouldn't filter out them in the clang
