configure: Check for static PIE support
Add SUPPORT_STATIC_PIE that targets can define if they support static PIE. This requires PI_STATIC_AND_HIDDEN support and various linker features as described in commit 9d7a3741c9e59eba87fb3ca6b9f979befce07826 Add --enable-static-pie configure option to build static PIE [BZ #19574] Currently defined on x86_64, i386 and aarch64 where static PIE is known to work.
