Comment (by rhaas):

 That was indeed an incorrect statement. I had read:
 {{{
 FFTW3_LIBS="fftw3"
 }}}
 instead of
 {{{
 : ${FFTW3_LIBS="fftw3"}
 }}}
 since I was completely unaware of the form ${parameter=word} and only knew
 of ${parameter:=word} so completely mis-parsed the code based on patterns
 of code that I expected to find. Bash's syntax is really quite strange, in
 particular since ":" is basically the command "true" so really we only
 need side effects and any do-nothing shell command would do.

 Being able to specify "odd" include directories (that are not called
 "include") from the option list is still required for using MKL though, so
 that configuration.ccl changes are still something I'd like to commit.
