Emit ARM build-attributes in the file scope (as header).
The ARM linker will check that .o files declare compatible
build attributes (e.g., all claim hard-float calling convention,
all claim VFP-vX ,etc.). Thus, in order to set up cross tests that
link LLC generated code against and Subzero generated code,
we need the build attributes to be compatible.
Pick ARMv7, hard-float calling convention, and neon, etc. which
we use for PNaCl LLVM.
Will probably have to reorganize to keep in sync once the ELF
writer also emits this.
