Comment 3 for bug 512504

The oddity of the double-entry of liboils_idl.la in the DEPENDENCIES line was reported about a year ago, and around that time, I did a shallow investigation of the Evergreen makefile system and found it to be written in a 'nonstandard' way. I got detoured into other work and never returned to fleshing out the problems.

I agree that the makefiles work as is, but the double entry hints at problems that will occur if a developer tries to make targets that are expected to work, but do not. I can review my year-old notes and make further comments.
