It's trying to find all the words in ${BUILDLINK_DEPENDS.${_pkg_}}
that contain '>=' but do not contain '{'. This is used in pkgsrc
to figure out what version of package "${_pkg_}" is required by
some other package.  I am not sure why the words that contain
'{' are skipped here; the commit log for revision 1.95 of
pkgsrc/mk/buildlink3/bsd.buildlink3.mk doesn't help me to understand
what "Don't spew files in the package directory" means.

Yes, \{ also seems to work with the version of make that I have lying around.
