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

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...

You may want -fno-PIE. -fno-PIE (with "f") affects code generation, but
"-no-pie" simply tells the linker not to link the executable as a PIE.

Hello Xi Ruoyao,
Your 3 patches are also fixing the regressions in the gcc-12 branch. Do you
plan on back-porting them on this release branch?

Richard: is it allowed to backport them (or the entire
https://gcc.gnu.org/pipermail/gcc-patches/2023-March/613093.html series) for
gcc-12?
