Absoft: Detect implicit link libraries on Linux and Mac

Use the "-X -v" flag to the Absoft front-end to pass "-v" to the gcc it
invokes under the hood.  Teach CMakeParseImplicitLinkInfo to exclude
linker version lines from consideration as link lines.  Fix parsing of
Sun's linker search path option "-Y..." to avoid conflict with the Mac
linker option "-Y<num>".
