When reviewing how this patch

	[PATCH] gcc: move assemble_start_function / assemble_end_function to output_mi_thunk
	https://gcc.gnu.org/ml/gcc-patches/2019-05/msg00722.html

might affect Solaris, I noticed an obsolete comment

     Note that use_thunk calls assemble_start_function et al.  */

that in one form or another is present in several targets, but has been
wrong for almost 10 years when r154736 ripped out those calls to
assemble_*_function in use_thunk.

The following patch corrects this.  Bootstrapped on i386-pc-solaris2.11
and sparc-sun-solaris2.11; I didn't bother to try and build cc1 on all
other affected targets, though.

Ok for mainline?  I guess this is obvious.

	Rainer
