libgloss/cris: Make C declarations present and match them

This is the libgloss part.
Recently, there was a change in gcc such that implicit function
declarations and type mismatches are now errors, no longer just
warnings.  Fix by adding and correcting declarations warned about;
including the right header or adding a declaration (for "main" in
lcrt0.c) and adjust to those types as necessary.
