FreeBSD compatibility (tensorflow#7073)

* Adding FreeBSD compatibility (non-breaking changes)

* Adding FreeBSD compatibility (BREAKING changes)
 - FreeBSD has libdl integrated into libc so -ldl is not available

* Adding FreeBSD compatibility (BREAKING changes)
 - FreeBSD has libdl integrated into libc so -ldl is not available

* - Define FreeBSD config
- Clear -ldl linkopts for FreeBSD only

* Clear -ldl linkopts for FreeBSD only

* Changing to local condition just as previously done with darwin

* Removing one indentation for syntax validation

* Removing one indentation here too

* - Changing new config name to lowercase
- Fixing buildifier warning
