DESTDIR has been abused for build purposes for a long time while, by design,
it should have only affected the installation. `buildworld' builds special
(cross) versions of compiler and tools that look things up under TOOLS_PREFIX.
As indicated in the commitlog for a relevant change to Makefile.inc1,v 1.240:
: (Attempt to move the "-nostdinc -I..." part of CFLAGS into the new CINCLUDES
: (modeled after a similar CXXINCLUDES) eventually failed because hard-coding
: ${WORLDTMP}/usr/include to be the first in the include list does not always
: work, e.g. lib/libbind.)
Because building of special versions of compiler and tools may not be easy
in picobsd, the following patch works around the problem in libbind and
should make things happy again:
