I am not sure if this would be more correct or have the PACKAGES contain 
something like ${EGLIBC_PACKAGE_MTRACE}, which could the be over-ridden 
by the yocto-tiny distro.

EGLIBC_PACKAGE_MTRACE ?= "${PN}-mtrace"

and then change ${PN}-mtrace in the PACKAGES list to 
${EGLIBC_PACKAGE_MTRACE}.

This exposes another "global", so I am not sure which is better.

Sau!
