Putting compiler ABI flags in anything other than $CC is still a "don't 
do that" situation, IMO.

I don't think there is a "right" answer here in general; you can find 
users who want it to work either way.

e.g. you might like to link a libapr against some malloc debugging 
library -lmyalloc, and expect to be able to switch in a new libapr which 
is not linked against said library.  That won't work if you find that 
everything linked against libapr is already linked against -lmyalloc.
