I don't know when you have tried the last time a GNU configure
script, but mostly all scripts do not use cc explicit but they
use the contents of the variable $CC if it is set so it can be
overwritten.

For instance running the configure scripts on DJGPP needs this
behaviour, because we have no cc but gcc.

Of course, if you really want to use all that platform dependent
compilers (not gcc) you have to live with the limitations which
come with these compilers. But if you switch to use only gcc, the
only compiler which runs on so many platforms (including that platforms
where also the other compilers run), you can use the configure script
and anything is configured for you automatically.
