right, it's much more often the exception than the rule that the correct order 
of -I/-L with system paths cause a failure ... ive seen it from time to time 
which is why when i architectured the Blackfin stuff, i made sure to do it 
properly from the get go: staging dir is completely treated as a system path 
with the toolchain, not an additional user path

i dont think comparing the cross-compile scenario here to the uClinux-dist is 
appropriate ... when you compile/install a package on your host, you install 
it into the system paths that are hardcoded into your host toolchain ... that 
is not done with uClinux-dist as there is no way you can assume the person 
compiling uClinux-dist has (or wants) write permission to the cross-toolchain 
directories ... so you have to use additional compiler flags so the 
cross-toolchain knows to treat the staging directory as a search path

so back to the original idea ... can we meet in the middle and have libraries 
install into a top level directory ($(ROOTDIR)/staging) and cut out the 
include/library symlinking ?
