I am applying this patch, approved by Jakub in a private email, to fix
the problem. With the patch applied, the specs file looks like this:
*asm_cpu:
%{mcpu=ultrasparc:%{!m64:-xarch=v8plusa}%{m64:-xarch=v9a -TSO}}
%{mcpu=v9:%{!m64:-xarch=v8plus}%{m64:-xarch=v9 -TSO}}
%{!mcpu=ultrasparc:%{!mcpu=v9:%{mcpu*:%{!m64:-xarch=v8}%{m64:-xarch=v9
-TSO}}}} %{!mcpu*:%(asm_cpu_default)}
*asm_cpu_default:
%{m64:-xarch=v9 -TSO} %{!m64:}
Cheers

Doh! Yes of course. Fixed as follows.

Confirmed. My build this morning on solaris2.7 with native "as"
errored out when building libgcc in stage1. The native assembler
doesn't accept -TSO and gives this message:

This cannot be right: only gas understands the -TSO flag (is this true for
all versions currently claimed to be supported on Solaris 2?), the native
as certainly does not. I suppose this belongs to sol2-gas-bi.h.

>Description:
64 bit binaries produced by gcc 3.x "-m64" option and compiled by gas are unusable for shared libraries, by default. The gas --help says "-TSO" is the default but it actually defaults to "-RMO". /usr/ccs/bin/ld will link the object files without any complaint, but the runtime linker barfs. This issue was first reported on
http://gcc.gnu.org/ml/gcc-help/2002-06/msg00005.html
Adding "-TSO" to the specs file for the appropriate -m64 clauses fixes the problem.
>How-To-Repeat:
$ gcc -m64 -c foo.c (any valid C code will do)
$ /usr/ccs/bin/ld -G -o foo.so foo.o
$ gcc -m64 -o main main.c ./foo.so
$ ./main
ld.so.1: ./main: fatal: ./foo.so: bad ELF flags value: 2
