Simplify COMMON_OBS by using list of sources

This introduces a new COMMON_SFILES variable, and then defines some of
COMMON_OBS in terms of this new variable.  This simpifies adding a new
ordinary source file.

ChangeLog
2017-11-27  Tom Tromey  <tom@tromey.com>

	* Makefile.in (COMMON_SFILES): New.
	(SFILES): Move some entries to COMMON_SFILES.
	(COMMON_OBS): Use COMMON_SFILES.
