Once gas_flag has been determined reliably on x86 and SPARC, the result
can be used to set gcc_cv_as_flags.
Tested on {i386,amd64}-pc-solaris2.11, sparc{,v9}-sun-solaris2.11,
{x86_64,i686}-pc-linux-gnu, amd64-pc-freebsd15.0, and
sparc64-unknown-linux-gnu.
Ok for trunk?
Again, this is very sensitive and error-prone, so all reviews and
testing are highly appreciated.
Thanks.
Rainer
