As noted in the PR, c.opt's description of -Wendif-labels erroneously

warn_endif_labels is used by:
  libcpp/directives.c: do_else
  libcpp/directives.c: do_endif
in which they use it to guard calls to check_eol_endif_labels.

It's not used by do_elif.

doc/cppwarnopts.texi gets this right:

Do not warn whenever an @code{#else} or an @code{#endif} are followed by text.
This sometimes happens in older programs with code of the form

This patch fixes the description in c.opt.

Successfully bootstrapped&regrtested on x86_64-pc-linux-gnu.

Committed to trunk as obvious (r246616).
