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.
