Well, there you missed a little tiny thing from the manual:
* LIBFOO_SOURCE may contain the name of the tarball of the package, which
Buildroot will use to download the tarball from LIBFOO_SITE. If
HOST_LIBFOO_SOURCE is not specified, it defaults to LIBFOO_SOURCE. If
none are specified, then the value is assumed to be
libfoo-$(LIBFOO_VERSION).tar.gz.
Notice the part about "If none are specified, then the value is assumed
to be libfoo-$(LIBFOO_VERSION).tar.gz" ? ;-)
So in your case, you must define GPIO_SOURCE to empty:
GPIO_SOURCE =
