The testcase in the current form doesn't FAIL without the patch on
x86_64-linux unless also testing with -m32; as that the 64-bit testing
on that target is probably way more common, and we can use also attributes
that FAIL without the patch with -m64, the following patch adjusts the
test, so that it FAILs without the patch for both -m64 and -m32 (but not
-mx32) and PASSes with the patch. Ok for trunk/10.2?
And for 9.4 with additional removal of the forgotten dg-options -m32 line?
Regtested on x86_64-linux and i686-linux.

* g++.dg/ext/attr-parm-1.C: Enable the test also for lp64 x86, use
sysv_abi and ms_abi attributes in that case instead of fastcall and
no attribute.
