    XFAIL 'offloading_enabled' diagnostics issue in 'libgomp.oacc-c-c++-common/reduction-5.c' [PR101551]
    
    Fix-up for recent commit 06b2a2abe26554c6f9365676683d67368cbba206
    "Enhance '_Pragma' diagnostics verification in OMP C/C++ test cases".
    Supposedly it's the same issue as in
    <https://gcc.gnu.org/bugzilla/show_bug.cgi?id=101551#c2>, where I'd
    noted that:
    
    | [...] with an offloading-enabled build of GCC we're losing
    | "note: in expansion of macro '[...]'" diagnostics.
    | (Effectively '-ftrack-macro-expansion=0'?)
