             Bug #: 11693
           Summary: cannot install without permissions to write to source
                    tree
           Product: new-bugs
           Version: 3.0
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: release blocker
          Priority: P
         Component: new bugs
        AssignedTo: unassignedbugs at nondot.org

When issuing make install as a privileged user, the installation script tries
to write to the source directory.

freundt at segen:pts/19:/home/src/devel/llvm-3.0.src> sudo make V=1 install

llvm[1]: Regenerating LibDeps.txt.tmp
/bin/sh: /home/src/devel/llvm-3.0.src/tools/llvm-config/LibDeps.txt.tmp:
Permission denied
make[1]: *** [/home/src/devel/llvm-3.0.src/tools/llvm-config/LibDeps.txt.tmp]
Error 1
make[1]: Leaving directory `/home/src/devel/llvm-3.0.src/tools/llvm-config'
make: *** [install] Error 1

Reproducible: always

How to reproduce:
1. run ./configure and make as a user that is allowed to write to the source
tree
2. run make install as a user that isn't allowed to write to the source tree

In my case the user root is allowed to write to /usr but NOT to the source tree
itself.
