several ports: clang include errors on 12

Hi

I was just about to post confirming ccache is not an issue; fails at same point.
Modifying ~jail/etc/libmap.conf (and re-snapshot) did not help either.

> That said, which ports are failing, in particular?
too many for complete list, but includes
llvm37,  qt5-qmake, openjpeg15, openjpeg, OpenEXR, ghostscript9-agpl-base
Sample fail log (OpenEXR):
