Remove DARWIN_PREFER_DWARF and dead code
This removes the always defined DARWIN_PREFER_DWARF and the code
guarded by it being not defined, removing the possibility to
default some i386 darwin configurations to STABS when it would
not be defined.
2021-09-10 Richard Biener <rguenther@suse.de>
* config/darwin.h (DARWIN_PREFER_DWARF): Do not define.
* config/i386/darwin.h (PREFERRED_DEBUGGING_TYPE): Do not
change based on DARWIN_PREFER_DWARF not being defined.
