             Bug #: 14313
           Summary: Custom project configuration error
           Product: tools
           Version: trunk
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: release blocker
          Priority: P
         Component: llvm-config
        AssignedTo: unassignedbugs at nondot.org
        ReportedBy: wojtek.danilo at gmail.com

According to http://llvm.org/docs/Projects.html setting custom project based on
LLVM should be easy, but it does not. The bundled makefiles and llvm-config
does not work properly.

STEPS TO REPRODUCE:
1) compile LLVM as described here:
http://llvm.org/docs/GettingStarted.html#getting-started
lets LLVM src folder = $LLVMSRC
2) cd $LLVMSRC/projects 
cp -R sample sample2
3) cd sample2/tools/sample
4) add to Makefile (before include $(LEVEL)/Makefile.common) following line:
LINK_COMPONENTS = all
5) cd $LLVMSRC/projects/sample2
6) mkdir build
7) cd build
8) ../configure (what is strange i see the first line of configure as:
"llvm-config .... no" - it is related to this bug)
9) make VERBOSE=1

as a result we should get our porgram compiled, but we get error, that
llvm-config could not be found. If I type llvm-config in terminal it works.

full verbose output:
 make VERBOSE=1
