cc-tool: add patch fixing boost.m4 logic for static linking

This commit adds a patch to cc-tool that fixes the boost.m4 logic used
to detect the linker rpath option so that it works properly with
static linking and additional libraries passed in LIBS.

This is the second step to fix static linking of cc-tool on
architectures like SPARC that need to link against libatomic:
