We should generate .note.gnu.property section with x86 assembly codes
for ELF outputs to mark Intel CET support when Intel CET is enabled
since all input files must be marked with Intel CET support in order
for linker to mark output with Intel CET support. Since nasm and yasm
can't generate the proper .note.gnu.property section, yasm-cet-filter.sh
and yasm-filter.sh are added to generate the proper .note.gnu.property
with linker help.
Verified with
$ CC="gcc -Wl,-z,cet-report=error -fcf-protection" CXX="g++ -Wl,-z,cet-report=error -fcf-protection" .../configure x86_64-linux
$ make -j8
on Linux/x86-64.
