configure: Enable compiler warnings to help add 'format' attribute
This attribute helps the compiler checking the type matching between
arguments and the specification in a printf-like format string, to
avoid invalid output. This attribute is optional, but some compilers
can suggest functions that could have it.
This patch adds the appropriate compiler flags if they are supported when
the source is being compiled with DEBUG enabled.
The patch also introduces a new macro WM_CFLAGS_CHECK_FIRST because in some
cases AX_CFLAGS_GCC_OPTION is not really efficient and in present case it
does not fits the job.
