 to deal with that in MPIR's `spkg-install`?  (I'd prefer the former, but
 am also undecided about the solution to choose on #16149, hence "needs
 info".)

 No, a slightly different one (but with the same effect).  `AC_PROG_CXX` in
 MPIR is now correctly called after `CXXFLAGS` have been saved, and MPIR
 now behaves correctly (I'd say).  But Sage sets (and exports) `CXXFLAGS`
 to the empty string, so MPIR doesn't touch them (again assuming they were
 intentionally set), such that we end up with missing flags (unless the
 user had really set them, or `CFLAGS`, to something meaningful).
