Fair enough :)

I suppose is semantics, and I may be wrong here, but my understanding 
was that EXTRA_xxxx vars were to be used from the command line to pass 
additional flags and/or override certain default flags, and that 
CFLAGS/LDFLAGS/LDLIBS were used from each app/example makefile to 
specify their own flags.

IMO we could achieve the correct order (ie. example/app 
CFLAGS/LDFLAGS/LDLIBS being added at the end to override default flags) 
without using EXTRA_xxxx vars from makefiles. Regarding this patch it 
would be pretty simple by just adding LDLIBS at the end of LDLIBS-y.
