I think this should be 'cm3' not 'stellaris', right?

I don't really like this, but I have no better idea either :-/

_MAKEVARS is deprecated. use _MAKE_OPT / _INSTALL_OPT
Also, I think you should expand PATH and then use
PREFIX=$(PTXCONF_CM3_GNU_TARGET)

or something like that.
-> no need for mkdir
-> strange umasks wont cause problems

The default targetinstall is empty, so this can be removed.
