This is something that would be nice to have, but when I looked at what 
it would take to do, the implementation was harder than it looked.  It 
does us no good to jam ${PKGSRC_CFLAGS} into the wrappers unless those 
flags are also filtered through the WRAPPER_TRANSFORMS to remove and 
change flags that can cause problems.  There is also the question of 
where on the command-line these ${PKGSRC_CFLAGS} would go.  There is 
already an imperfect mechanism _WRAP_EXTRA_ARGS.CC that appends to the 
end of the compiler command-line, but that is not always the right thing 
to do.

FWIW, I'm in the middle of rewriting the wrapper and compiler frameworks 
to fix a PR.  I'm still not sure how to address the issue of injecting 
arguments into the command-line without making the wrappers have some 
deeper understanding of the tools they are wrapping.
