Replace --enable-static-pie with --disable-default-pie

System Internals / glibc - Siddhesh Poyarekar [sourceware.org] - 13 December 2021 02:38 UTC

Build glibc programs and tests as PIE by default and enable static-pie automatically if the architecture and toolchain supports it.

Also add a new configuration option --disable-default-pie to prevent building programs as PIE.

Only the following architectures now have PIE disabled by default because they do not work at the moment. hppa, ia64, alpha and csky don't work because the linker is unable to handle a pcrel relocation generated from PIE objects. The microblaze compiler is currently failing with an ICE. GNU hurd tries to enable static-pie, which does not work and hence fails. All these targets have default PIE disabled at the moment and I have left it to the target maintainers to enable PIE on their targets.

build-many-glibcs runs clean for all targets. I also tested x86_64 on Fedora and Ubuntu, to verify that the default build as well as
--disable-default-pie work as expected with both system toolchains.
