[llvm] r197684 - llvm-config: Don't show build tree with --obj-root for installed llvm-config. Show $(prefix) instead.

[NAKAMURA Takumi]

I know I broke dragonegg builders.

They are using installed llvm, although "make install" does not
provide utils, FileCheck &c.
I wonder how I could tweak buildsteps. Please be patient.

IMO, dragonegg's make-check should use not installed llvm, but build tree.
