The g++.dg/gcov/pr16855*.C tests FAIL on Solaris:

Same for -std=gnu++98.
The issue has long been known and the failures generate an excessive
amount of noise. Since the PRs haven't seen any activity in years, this
patch xfail's them.
Tested on i386-pc-solaris2.11, sparc-sun-solaris2.11,
x86_64-pc-linux-gnu, and x86_64-apple-darwin25.1.0.
Committed to trunk.
I've tried to fix this myself several times, but never got anywhere, so
this is beyond me.
