[issue15127] Supressing warnings with -w "whether gcc supports ParseTuple"

[Samuel John]

New submission from Samuel John <python at samueljohn.de>:

In configrue.in, Python checks if the compiler supports __attribute__((format(PyArg_ParseTuple, 2, 3))) and sets the CFLAGS to "CFLAGS -Werror" to decide this test.

When you build Python with "CFLAGS=-w" (homebrew's default), configure reports 

    whether gcc supports ParseTuple ... yes

which is not supported for clang (I was told).

I know it's hard to remove a certain flag from the CFLAGS, but perhaps there should be better documentation about this issue.
