Fixed link bugs in BlueGeneP build. 

- Build wasn't properly using -soname linker args, so installed libraries
  could depend on relative paths from the build directory.
- Consolidated GNU linker args to one place in the BlueGeneP-base platform
  file, since ld is used by both XL and GNU toolchains on BlueGene.
