Fix long file name bug reported on SCO Open Desktop 2.0 by Ulf Lunde

Browse Source 
<Ulf.Lunde@kvatro.no> and Dag H. Wanvik <Dag.H.Wanvik@kvatro.no>.

* coffread.c (getfilename):  Eliminate COFF_NO_LONG_FILE_NAMES
test, which is apparently left over from when we used native
include files and couldn't depend on the member names being there.
* tm-3b1.h, tm-altos.h, tm-i386v.h:  Don't set it.

ALso fix this in tm-i860.h which isn't ChangeLogged since it's sanitized out
for lack of paperwork.

* mipsread.c: Major overhaul to use new BFD symbol table reading
routines. Now swaps information as it is needed, rather than
swapping everything when the file is read.
Thu Feb 4 01:52:36 1993 John Gilmore (gnu@cygnus.com)
* Makefile.in (TARDIRS): Add sparclite demo dir.
