Providing that during ./configure Py_DEBUG can either be set or not, but there is no third state, which third state would justify calling ./configure --with-pydebug=lambda, --with-pydebug shall be renamed to --enable-pydebug .

Likewise for --with-pymalloc , but it is more tricky.  Currently ./configure --help emits "--with(out)-pymalloc    disable/enable specialized mallocs".  Usually from the output of ./configure --help one shall be able to conclude, whether a switch is on or off by default, if it is not provided.  E.g. if it is by default off, then "--enable-X   enable feature X" is printed; and "--disable-Y disable feature-Y" is printed when by default the feature is on.

The code says, that if pymalloc is enabled implicitly, if neither --with-pymalloc nor --without-pymalloc is provided.  Let's update the AS_HELP_STRING to show the default and also shorten the code, which makes it also easier to understand (for me at least)
