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.
