        * sanitizer_common/sanitizer_linux_libcdep.cc (__GLIBC_PREREQ):
        Define if not defined.
        (DL_INTERNAL_FUNCTION): Don't define.
        (InitTlsSize): For __i386__ if not compiled against glibc 2.27+
        determine at runtime whether to use regparm(3), stdcall calling
        convention for older glibcs or normal calling convention for
        newer glibcs for call to _dl_get_tls_static_info.
