Subject: [Patch ARM/ configury] Add fall-back check for gnu_unique_object - Default to this for arm-linux-gnueabi

Hi,

While investigating a report for odd behaviour with a C++ program, I
discovered that the automatic checking for gnu_unique_object is broken
during
bootstrap for arm-linux-gnueabi targets because on ARM '@' is a
comment character for the assembler.

I do realize this can be worked around with the configure time option
but it would be nice to fix this without
having to resort to the workaround everytime.

Fixed thusly - tested with bootstraps on both arm-linux-gnueabi and
verified that auto-host.h has the right definition.

Ok ?

regards,
Ramana

       * config.gcc (target_type_format_char): New. Document it. Set it for
         arm*-*-* .
       * configure.ac (gnu_unique_option): Use target_type_format_char in test.
       * configure: Regenerate .
