Rather than put the empty function in every affected target file, I
found it cleaner to simply move the function outside the macro guards
in dwarf2out.c.  I also fixed some #endif comments I came across while
reading this code.

Okay to install?

	* dwarf2out.c (PTR_SIZE, default_eh_frame_section): Move outside
	of macro guards. Fix #endif comment.

	* output.h (default_exception_section, default_eh_frame_section):
	Move prototypes outside of macro guard.
	
	* crtstuff.c: Fix #endif comment.
