Subject: Try harder to save memory, add ix86 to 'save memory' list


As per the other llvm packages, use ld flags that prioritize
memory use over performance for memory-impaired arches. Also add
ix86 to the list of memory-impaired arches, as my Rawhide build
attempt died on i686 due to lack of memory:
