llvm-6502/utils/llvm-config/Makefile
Reid Spencer b195d9d365 Update to llvm-config tool, by Erik Kidd:
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.
