clang revision 135360
>Description:
security/nettle builds fine with clang on amd64 but fails on i386 because clang cannot decide on the size of a 'sub' instruction.

>How-To-Repeat:
Try to build security/nettle on i386 with CC=clang and CXX=clang++
>Fix:
Instruct clang to use the correct variant of the 'sub' instruction.
