Fix testsuite issues with --enable-default-ssp

Add -fno-stack-protector to dg-options where needed.  Fixes the following
testsuite failures from adding --enable-default-ssp to configure:

Fix testsuite issues with --enable-default-pie

The following failure are seen in gcc-11.2 when building with
--enable-default-pie:

FAIL: gcc.target/i386/cet-sjlj-6a.c scan-assembler-times movq\\t.*buf+8 1
FAIL: gcc.target/i386/cet-sjlj-6a.c scan-assembler-times subq\\tbuf+8 1

FAIL: gcc.target/i386/fentryname3.c scan-assembler 0x0f, 0x1f, 0x44, 0x00, 0x00
FAIL: gcc.target/i386/pr24414.c (test for excess errors)
FAIL: gcc.target/i386/pr93492-3.c scan-assembler
\\t.cfi_startproc\\n\\tendbr(32|64)\\n.*.LPFE1:\\n\\tnop\\n1:\\tcall\\t__fentry__\\n\\tret\\n
FAIL: gcc.target/i386/pr93492-5.c scan-assembler
\\t.cfi_startproc\\n.*.LPFE1:\\n\\tnop\\n1:\\tcall\\t__fentry__\\n\\tret\\n
FAIL: gcc.target/i386/pr98482-1.c scan-assembler movabsq\\t\$__fentry__,
%r10\\n\\tcall\\t*%r10

Adding -no-pie to dg-options only fixed pr24414.c.  For the rest I added a "{
target { ! pie_enabled } }" to the failing tests, which may or may not be the
proper solution...
