But not phase 1? Interesting. What target does clang --version on the phase 1 compiler print?

The problem is we "guess" that the host architecture is i686, and fail when we find out that we can't target it (i686 is not defined). This guess originates from gethosttriple() call in cmake/modules/GetHostTriple.cmake. Probably, it makes sense to fix that to return i568 on openSUSE, and then test for i586 in the same way we already test for i386/i686.

Maybe try targeting both i686 and i586 unless that would break something else?
