3c7d306488 Revert previous change. It doesn't work because it neglects to
consider there may be a file compiled without -g screwing things up
(e.g. we are looking for the minimal symbol for "main" and we get the
one for "start" instead).

basis.  See comments in objfiles.h and details in ChangeLog.  Also remove
redundant definitions of FRAME_CHAIN_VALID from most of the tm-* files and
use a default definition in frame.h.
