Features: On SunPro link feature check with lang std flag
Follow up commit e17b179184 (Features: On SunPro link with language
standard compiler flag, 2017-04-28) to apply the same fix to the feature
checks. The `try_compile` used for these is intentionally not using
`CXX_STANDARD`-based logic so that it can test the individual flags.
