   I wonder if this means that some of those dg-skip-if in the other
testcases passing -ffunction-sections are just stale entries from
the depreciated a.out support? Does anyone know if rs6000-*-aix*,
powerpc*-*-aix* and hppa*-*-hpux* currently support function sections?
Also it is strange that rs6000-*-aix* and powerpc*-*-aix* skip
g++.dg/eh/gcsec1.C and gcc.dg/special/gcsec-1.c but hppa*-*-hpux*
skips gcc.dg/ucnid-12.c. Not really coherent.
