complibs/ppl: only add -fpermissive flag to CXXFLAGS

-fpermissive is not a valid option to gcc.

Adding it to the CFLAGS make the ppl checks fail with the following
error:

[ALL  ]    Making check in tests
[ALL  ]    cc1: warnings being treated as errors
[ERROR]    cc1: error: command line option "-fpermissive" is valid for C++/ObjC++ but not for C
[ALL  ]    cc1: warnings being treated as errors
[ERROR]    cc1: error: command line option "-fpermissive" is valid for C++/ObjC++ but not for C
[ERROR]    make[7]: *** [formatted_output.o] Error 1
