this seems to be related to the confusion of CFLAGS, CPPFLAGS and CXXFLAGS.
- CPPFLAGS flags for the C PreProcessor (and C++ and objective C/C++
preprocessors)
- CFLAGS flags for the C compiler
- CXXFLAGS flags for the C++ compiler

since abl_link~ is a C++-external, the CFLAGS don't have any effect and
you should use CXXFLAGS instead.

CFLAGS should override categories optimization.flags arch.c.flags. You can
inspect accumulated c.flags and cxx.flags by using "make vars CFLAGS="-O0
-g". For me on Xubuntu that gives:

c.flags = -DPD -I "/usr/include/pd" -DUNIX  -fPIC  -O0 -g
cxx.flags = -DPD -I "/usr/include/pd" -DUNIX  -fPIC -fcheck-new  -O0 -g
