ld.so: Add architecture specific fields
To support Intel Control-flow Enforcement Technology (CET) run-time control: 1. An architecture specific field in the writable ld.so namespace is needed to indicate if CET features are enabled at run-time. 2. An architecture specific field in struct link_map is needed if CET features are enabled in an ELF module. This patch adds dl-procruntime.c to the writable ld.so namespace and link_map.h to struct link_map. Tested with build-many-glibcs.py. * elf/dl-support.c: Include <dl-procruntime.c>. * include/link.h: Include <link_map.h>. * sysdeps/generic/dl-procruntime.c: New file. * sysdeps/generic/link_map.h: Likewise. * sysdeps/generic/ldsodefs.h: Include <dl-procruntime.c> in the writable ld.so namespace.
