https://github.com/llvm/llvm-project/issues/67767

The optimization in https://github.com/WebKit/WebKit/pull/15830 apparently does not compile for armv7 due to a Clang compiler bug.

I propose ensuring __arm__ is not defined to work around this issue unless this bug is fixed since WebKit still has an armv7 build.
