Hello Mark,

Re-tested with buildroot 2019.02.1, seems for python-3.7.2 the compile
with pymalloc seems to be the default, no explicit '--with-pymalloc'
given, but config.log states:

	configure:11486: checking for --with-pymalloc
	configure:11506: result: yes

And from configure:

	if test -z "$with_pymalloc"
	then
	    with_pymalloc="yes"
	fi

So for your case add the 'm', in case you want to provide your
package patch for upstream buildroot then without 'm'....

Regards,
Peter
