Thanks for the hint, I'll add some tests to
https://github.com/NetBSD/src/blob/trunk/usr.bin/make/unit-tests/varmod-subst.mk
to demonstrate that the :S modifier only does a simple substring search,
without any placeholders other than the anchors ^ and $.

To get extended regular expressions, use :C instead of :S.  For more
details, as Jonathan already pointed out, see the manual page for make
or bmake.  There is nothing pkgsrc-specific going on here.
