Well I don't have the whole answer to this thing, but I have a machine
that did a "make world" successfully but failed a "make release". My
/etc/make.conf have "CFLAGS= -O2 -pipe" but I don't do anything
special for "make release", because that is the snaps that end up on
internat. (The script that is run in the chroot environment to do
everything during the "make release" do a "export CFLAGS='-O -pipe'".)

It looks like during my "make world" the gnu/usr.bin/perl/perl/Makefile
didn't pick up the -nostdinc that is being set in src/Makefile.inc1, but
it was picked up during the "make release", but the -I${DESTDIR}/usr/include
that is added to CFLAGS in bsd.prog.mk isn't picked up, so it does not
know where to find the normal include files.

Exactly why I don't know. Perhaps the fact that bsd.prog.mk is included
halfway in the gnu/usr.bin/perl/perl/Makefile may have something to
do with it???
