Chuck Atkins 928d2085d8 CrayPrgEnv: Don't use absolute paths for imlicit libraries
When parsing implicit include dirs, link dirs, and link libs, all
arguments are resolved to absolute paths instead of relative paths.
This is correct for link and include directories but link libraries
should only include the library name, not it's path.
