1. Check for Perl and only build llvm-config if its available. 2. Add some virtual components 3. Don't depend on "standard" location for Perl, but configured location 4. Document the tool with a POD file. This version is now ready for testing by users. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@27005 91177308-0d34-0410-b5e6-96231b3b80d8
