i386: Update I386_USE_SYSENTER for early PIC syscall
Define I386_USE_SYSENTER to 0 or 1 so that special versions of syscalls with "int $0x80" can be provided for static PIE during self relocation. Also check PIC instead SHARED for PIC version of syscall macros. * sysdeps/unix/sysv/linux/i386/sysdep.h (I386_USE_SYSENTER): Define to I386_USE_SYSENTER to 0 or 1 if not defined. (ENTER_KERNEL): Check if I386_USE_SYSENTER is 1 and check PIC. (INTERNAL_SYSCALL_MAIN_INLINE): Likewise. (INTERNAL_SYSCALL_NCS): Likewise. (LOADARGS_1): Likewise. (LOADARGS_5): Likewise. (RESTOREARGS_1): Likewise. (RESTOREARGS_5): Likewise.
