Subject: Tru64 cdrom and pthread option fix

SDL-1.2.7/src/cdrom/osf/SDL_syscdrom.c Fixes
Some CD-ROM drives(ex. TEAC CD-532E) cannot play
first 150 frames(aka gap).
CheckDrive() fix.
The end of comment is "* /" in AddDrive().

SDL-1.2.7/configure.in Fixes
Add *-*-osf pthread option and
delete line SDL_LIBS="$SDL_LIBS -lrt".
