[PATCH 1/1] Add "&" asm constraint modifier to ASM_MUL outputs

[Rob Browning]

Without this change, building for arm{hf,el} with gcc-4.9 (Debian
4.9.1-14) fails as follows:

  /tmp/ccdZTkXQ.s:14591: rdhi, rdlo and rm must all be different

Thanks to Mark H Weaver <address@hidden> for the suggestion.

 This should apply against 2.0.11.
