[v3] XFAIL 27_io/basic_ostream/inserters_arithmetic/char/hexfloat.cc on Solaris (PR libstdc++/64054)

[Rainer Orth]

The 27_io/basic_ostream/inserters_arithmetic/char/hexfloat.cc currently
FAILs on Solaris

FAIL: 27_io/basic_ostream/inserters_arithmetic/char/hexfloat.cc execution test

As determined in the PR, this happens because Solaris only supports
hexfloats in C99 mode, but gcc doesn't correctly link with values-xpg6.o
in that case (PR target/40411).  Until that is fixed, the test is
XFAILed.

Tested with the appropriate runtest invocations on i386-pc-solaris2.11
and x86_64-unknown-linux-gnu, installed on mainline as preapproved by
Jonathan in the PR.
