[testsuite] tolerate enabled but missing language frontends

[Alexandre Oliva <oliva@adacore.com>]

When a language is enabled but we run the testsuite against a tree in
which the frontend compiler is not present, help.exp fails.  It
recognizes the output pattern for a disabled language, but not a
missing frontend.  Extend the pattern so that it covers both cases.

Tested on x86_64-linux-gnu.  Ok to install?

	* lib/options.exp (check_for_options_with_filter): Handle
	missing frontend compiler like disabled language.
