This helps compiling the code with older gcc especially on older build
hosts, additionally clang advertizes itself as gcc 4.2.1 so it helps
compiling dependent modues using clang as well

This patch fixes the following error:

  .../lib/arm/setjmp.S:18: Error: unrecognized symbol type ""
  .../lib/arm/setjmp.S:26: Error: unrecognized symbol type ""

The problem is the assembly syntax that is used is not portable to ARM,
where the '@' symbol is a comment:

  > Note on targets where the @ character is the start of a comment
  > (eg ARM) then another character is used instead. For example the
  > ARM port uses the % character.
