It used to make sense to me, as I am doing tests on more configurations of picolibc and some of them do provide all the necessary macros (e.g. armv7m with fpu). Now, I realize this is not that useful for libc++ itself, as only one configuration is tested in CI here.

Yet, still I will switch from XFAIL to UNSUPPORTED to cater the configurations, where this test would pass.
