cc1obj: Make Objective C the default language.

[Neil Booth]

Ovidiu,

This bootstraps without regressions.  It seems that objc-act.c wants
to behave as both a C compiler and Objective C compiler - is this
right?  There are a lot of conditionals based on "doing_objc_thang".
With this patch, cc1obj only does Objective C.

So, two questions:

1) OK to commit?

2) Would you accept a follow-up patch to remove the (redundant)
Objective C "thang" tests for code in /objc?

Neil.

	* c-decl.c (c_decode_option): Don't handle -lang-objc.
	* objc/lang-options.h: Remove -lang-objc.
	* objc/lang-specs.h: Don't pass -lang-objc to cc1obj.
	* objc/objc-act.c (lang_init_options): Set c_language.
