The problem is -m64 overrides -mx32.

I got rid of the error with the following patch

 struct gomp_task

AFAICT -mx32 is not supported on darwin.

No, this is certainly wrong: I'm seeing the same failure on
i386-pc-solaris2.1[01]
(cf. PR testsuite/53365) and i686-unknown-linux-gnu.

The same failure also occurs for

FAIL: gcc.target/i386/pr53249.c (test for excess errors)
Excess errors:
/vol/gcc/src/hg/trunk/local/gcc/testsuite/gcc.target/i386/pr53249.c:1:0: error:
address mode 'short' not supported in the 64 bit mode

also on i386-pc-solaris2.1[01] and i686-unknown-linux-gnu.  There's something
amiss that's not darwin-specific.
