+Subject: build: define STAMP_CONFIGURED recursively
+
+Defining STAMP_CONFIGURED statically caused it not to reflect changes to
+PKG_CONFIG_DEPENDS made after including package.mk, like the additional options
+added by feeds.mk for all packages.
+
+Furthermore, as STAMP_CONFIGURED_WILDCARD was already defined recursively, the
+patsubst in its definition would never match, and in consequence, the stamps
+were never removed. This caused packages not to be rebuilt when they should have
+been.
