unfortunately, the dg-xfail-run-if is wrong. E.g. it causes XPASSes on
i386-pc-solaris2.11.
You should base this on the cpu part of the triplet in general, not on
the OS. Besides, according to gcc-testresults postings, the test FAILs
on other targets as well: armv8l-unknown-linux-gnueabihf, hppa*, and ia64.
Besides, unless you want to introduce an effective-target keyword (with
documentation in sourcebuild.texi), probably overkill for a single use,
you can have more than one dg-xfail-run-if line to improve readibility.
