True, but it's often way simpler to discuss testcase issues in the
original PR rather than open new PRs for every single issue with a
testcase (and there's already been the comment character one here).

Seems like an option, too (and would work on other affected targets
should they appear).  Tested on sparc-sun-solaris2.11 with as and gas.

Btw., I wonder which of the targets currently skipped with "split DWARF
unsupported" are instances of this problem, too: Solaris doesn't support
-gsplit-dwarf, still the test PASSes on Solaris/SPARC with gas and
Solaris/x86 with either assembler.
