[Bug target/17139] New: Bootstrap fails on darwin with "as" version previous to cctools-500

["kcook at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

A recent patch (http://gcc.gnu.org/ml/gcc-patches/2004-08/msg01341.html) adds in
support for the darwin assembler directive .subsections_via_symbols within GCC.

This causes a bootstrap failure on my system's version of as (Apple Computer,
Inc. version cctools-490.obj~3, GNU assembler version 1.38) and presumedly with
all versions of Apple's as prior to cctools-500 where this pseudo-op support was
recently added according to
http://darwinsource.opendarwin.org/WWDC2004/cctools-523/RelNotes/Private_CompilerTools.html
