pkgsrc does not provide a "python3" binary by default, if you're not
using pkg_alternatives.

However, for building from pkgsrc, lang/python/tool.mk provides one.
This was until recently included from devel/meson/build.mk, but it's
not needed everywhere.

The fix is to include the file directly in chat/hexchat/Makefile, i.e. add

PYTHON_FOR_BUILD_ONLY=	  tool
.include "../../lang/python/tool.mk"

to the Makefile.

(If hexchat needs python at runtime, do not add the
PYTHON_FOR_BUILD_ONLY line.)
