[LLVMbugs] TOOLLINKOPTSB from Makefile.config is put several places on the command line

[Reid Spencer]

Hi Henrik.

Interesting. And here I was thinking no one used TOOLLINKOPTSB :)

Anyway, the problem you're seeing is that TOOLLINKOPTS was getting inserted 
into LDFLAGS twice. Once incorrectly and once correctly. I'm working on a patch 
to correct that right now.
