It seems to me like this would break VPATH builds since it assumes
you're building in the source dir.

You could create a plain static Makefile in the patches directory and
then add 'patches' to the beginning of SUBDIRS ahead of ".".  This
Makefile's only task would be to patch in $(srcdir) for the 'all'
target, patch in $(distdir) for the 'distdir' target, and provide empty
rules for all the other required targets as explained in the manual
section "Third-Party Makefiles".
