Use <startup.h> in __libc_init_secure
Since __libc_init_secure is called before ARCH_SETUP_TLS, it must use "int $0x80" for system calls in i386 static PIE. Add startup_getuid, startup_geteuid, startup_getgid and startup_getegid to <startup.h>. Update __libc_init_secure to use them. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>
