The two patches provide following: - enable sse on amd64 (the use flag is deactivated, forgot it?) - enable parallel make by fixing the offending makefile (isn't it lame to disable a feature instead of fixing it?). Tested using make -j10 on dual core. - fix using configured compiler in the makefile instead of "cc" (Note: I use paludis not portage, so following infos might be outdated.)

Created attachment 102211 [details, diff] proper deps
Created attachment 102213 [details, diff] sse + parallel builds
Created attachment 102216 [details, diff] really proper deps Former patch contained a typo and deps for two files were missing.
We are in process of de-masking the flag again, actually, if you use portage 2.1.2_{pre|rc}* it already is, so I'd rather not hard-enable it just to switch back again.
I should note that my patch got merged upstream, so hello maintainer?
Applied, sorry for the delay. As Simon said, I didn't force sse on amd64 to let them handle that properly. Thanks for reporting here and upstream (which is more important imho)
