Add -z cet-report=[none|warning|error] to report the missing Intel
Indirect Branch Tracking (IBT) and Shadow Stack (SHSTK) properties
in input .note.gnu.property section. -z cet-report=none, which is
the default, will make the linker not report missing properties in
input files. -z cet-report=warning will make the linker issue a
warning for missing properties in input files. -z cet-report=error
will make the linker issue an error for missing properties in input
files. Note that -z ibt will turn off the missing IBT property report
and -z shstk will turn off the missing SHSTK property report.
Supported for Linux/i386 and Linux/x86_64.
