It is.

Make first tries the path relative to the including file, as documented
in the manual page. In usr.bin/make/parse.c, that's implemented in
IncludeFile and FindFileRelative.

If that fails, it tries the path relative to ${.CURDIR} as a fallback.
This fallback is not documented in the manual page, though.

I verified this by adding this line at the top of mk/bsd.pkg.mk:
> .sinclude "../../does-not-exist.mk"

When I ran 'make -v MAKE' in a package directory, make first searched
for '../../../does-not-exist.mk' (outside pkgsrc), falling back to
'../../does-not-exist.mk'.

Same for bmake from pkgsrc.
