_ELIX_LEVEL problems

[Jeff Johnston]

Aha.  I found the problem.  The $(ELIX_SOURCES) is missing from 
lib_a_SOURCES.  This was due to my change recently to fix the problem 
with the object prefix being added properly to all objects.  I'll start 
checking the other libc directories to ensure that I didn't mess those 
up as well.

Patch checked in.
