Help texts should end with ".". This may not cause a test failure in this
particular case because help texts for Driver options aren't actually used
(and the test for help text formatting checks the --help output, not the
.opt files); you actually need to update gcc.c:display_help to get a help
text in the driver's --help output.
Since none of the related options such as -nostdlib are mentioned in that
--help output, either removing the help text or adding "." would seem
appropriate. Or add all those options to --help output separately.

There are lots of other LINK_GCC_C_SEQUENCE_SPEC definitions for
particular targets I'd expect to be updated.
