H.J. Lu 9e38f455a6 x86: Add --enable-cet=permissive
When CET is enabled, it is an error to dlopen a non CET enabled shared
library in CET enabled application.  It may be desirable to make CET
permissive, that is disable CET when dlopening a non CET enabled shared
library.  With the new --enable-cet=permissive configure option, CET is
disabled when dlopening a non CET enabled shared library.

Add DEFAULT_DL_X86_CET_CONTROL to config.h.in:

 /* The default value of x86 CET control.  */
 #define DEFAULT_DL_X86_CET_CONTROL cet_elf_property

which enables CET features based on ELF property note.

--enable-cet=permissive it to

 /* The default value of x86 CET control.  */
 #define DEFAULT_DL_X86_CET_CONTROL cet_permissive

which enables CET features permissively.

Update tst-cet-legacy-5a, tst-cet-legacy-5b, tst-cet-legacy-6a and
tst-cet-legacy-6b to check --enable-cet and --enable-cet=permissive.
