Is it a drawback at all? I don't think so.

Mmh, you're computing "$$($(2)_RAWNAME)-$$($(2)_VERSION)" three times
in a few lines. And it's also computed elsewhere:

package/pkg-generic.mk:156:$(BUILD_DIR)/%/.stamp_patched: NAMEVER = 
$(RAWNAME)-$($(PKG)_VERSION)
package/pkg-generic.mk:427:  $(2)_SOURCE                        ?= 
$$($(2)_RAWNAME)-$$($(2)_VERSION).tar.gz
package/pkg-generic.mk:485:$(2)_REDIST_SOURCES_DIR = 
$$(REDIST_SOURCES_DIR_$$(call 
UPPERCASE,$(4)))/$$($(2)_RAWNAME)-$$($(2)_VERSION)
package/pkg-generic.mk:821:     @$$(call 
legal-manifest,$$($(2)_RAWNAME),$$($(2)_VERSION),$$($(2)_LICENSE),$$($(2)_MANIFEST_LICENSE_FILES),$$($(2)_ACTUAL_SOURCE_TARBALL),$$($(2)_ACTUAL_SOURCE_SITE),$$(call 
UPPERCASE,$(4)))

We should compute it once and store it in a new per-package variable.

BTW, I tested this patch and it works, but I'd like to give my
"Tested-by" tag after you do these changes, thanks.
