src_compile() builds the sandbox but then in src_install(), make clean is run followed by a make install ... this results in src_compile() building the sandbox with arch-specific options but then having src_install() turn around and blow it all away ... also, there's no point to `make clean` in the first place afaik
I noticed this the other day as well; looks like it's been around for a while: http://bugs.gentoo.org/show_bug.cgi?id=43368
