x86: Check static link of dynamic objects
...
On Linux/x86, when -static is passed to gcc, gcc passes it to linker
before all input files suitable for creating static executable. X86
linker will report error for dynamic input objects if -static is passed
at command-line before all input files without --dynamic-linker unless
--no-dynamic-linker is used.

* elf-linker-x86.h (elf_linker_x86_params): Add
static_before_all_inputs and has_dynamic_linker.
* elfxx-x86.c (_bfd_x86_elf_link_setup_gnu_properties): Report
dynamic input objects if -static is passed at command-line
before all input files without --dynamic-linker unless
--no-dynamic-linker is used.

x86: Add -z cet-report=[none|warning|error]
...
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.
