When all the codepaths using manually set .arch/.fpu code is
behind runtime detection, the elf attributes should be suppressed.
This allows tools to know that the final built binary doesn't
strictly require these extensions.

Ideally, these should only be added on platforms where we have
runtime detection (i.e. linux). So on non-linux, ELF platforms,
they should in theory be omitted. Adding #ifdef __linux__ around
them do feel like overkill though.
