Yeah, good stuff.  My little ploy seems to have worked :)  Thanks.

Well, I seem to have trouble with the flag-compare code.  libdl.oS 
doesn't seem to build here (i386 default config), it doesn't get the 
-Ildso/ options passed.  Before that ldso.oS and resolve.oS are rebuilt 
every time.  Not sure if that's breakage local to my tree, but "svn 
diff" is clean and the tree is uptodate.

I'm also not sure I understand how the flag-compare code works, or how 
it ensures things are rebuilt when the flags do match.
