I was wrong.  Please replace OEDIR by OMDIR.  You don't need to set
OEDIR nor OMDIR.

some confirmation:

did you run make update before compilation?

could you send me this file:

/projects/openmoko/moko/tmp/work/x86_64-linux/gmp-native-4.2.1-r2/temp/log.do_compile.27458

as indicated in the debug output?

by the way, 1191 is the number of tasks.  there are about multiple
tasks for 1 package, so actually OE is just doing what's necessary.
dm2 also needs glib, gtk, xft and of course we need crosstools, etc.
so this number is quite reasonable.
