FYI: I removed meta-gumstix-community from my layers and ran

MACHINE="beagleboard" bitbake omap3-sgx-modules

and get same:

| make[3]: *** No rule to make target
needed by `/home/Superandy/tmp/oe-core-eglibc/work/beagleboard-angstrom-linux-gnueabi/omap3-sgx-modules/'.

so I think it is related to changes in other layers. Did you test with
master or danny?
