This is just a heads-up on some uncommitted work that I'm still working
on.  I was working on a less compiler-centric solution to this problem
that involved creating special headers files in ${BUILDLINK_DIR}/include
and depending on pkgtools/libnbcompat.  For example, if a platform lacks
asprintf(), we search the header search path for <stdio.h>, then create
a ${BUILDLINK_DIR}/include/stdio.h that looks like:

#include <nbcompat.h>
#include "/usr/include/include/stdio.h"	  /* path to <stdio.h> */

I could just as easily use libiberty instead of libnbcompat since the
former is probably better maintained.  All of this is encapulated in a
single Makefile that was to be included for
particular platforms, e.g. IRIX, HP-UX, etc.

This originally came up because pkgsrc on IRIX 5 was stalling due to thd
system libraries missing many functions that are expected in a more
modern UNIX system.  I was trying to think of a non-intrusive way to
augment the system libraries and headers with a library that provided
these missing functions, and also to avoid needing to change a lot of
packages to make this work.
