Hm, I had the idea that we were already asking ExtUtils::Embed for that,
but now I see we only inquire about LDFLAGS not CCFLAGS. Yes, this sounds
like a promising avenue to pursue.
It would be useful to see the results of
perl -MExtUtils::Embed -e ccopts
on one of the affected installations, and compare that to the problematic
field(s).
