Sorry about the regression.
I installed the patch below to skip the test if the target is not x86_64
in lp64, as obvious. This should fix the issue.

Subject: [PATCH] testsuite: fix gcc.c-torture/compile/libcall-2.c in -m32
This test relies on having __int128 in x86_64 targets, which is only
available in -m64.
gcc/testsuite/ChangeLog
* gcc.c-torture/compile/libcall-2.c: Skip test in -m32.
