	Avoid compilation errors in MinGW native builds

	The error is triggered by including python-internal.h, and the
	error message is:

	     In file included from d:\usr\lib\gcc\mingw32\6.3.0\include\c++\math.h:36:0,
		      from build-gnulib/import/math.h:27,

	using ::hypot;
		^~~~~

	This happens because Python headers define 'hypot' to expand t
	'_hypot' in the Windows builds.
	* python/python-internal.h (_hypot) [__MINGW32__]: Define back to
	'hypoth'.  This avoids a compilation error.
