How then are we going to insert custom compiler flags?

Inserting custom compiler flags is usefull tu test new compiler features or 
such. For example testing C++11 before it was supported by Qt, testing 
analyzer toolr. Using clang plugin such as clazy or other ctatic analyzers. Or 
trying out afl (the fuzzer, ok, IIRC this was only changing $CXX and $CC).

There should be an alternative. And i don't think editing the configure script 
is a good one.
(Unless there is already an alternative which I don't know of.)
