* sysdeps/unix/sysv/linux/i386/sysdep.h (SYSCALL_ERROR_HANDLER):
New macro. (PSEUDO): Use it instead of SYSCALL_PIC_SETUP and jmp syscall_error. * sysdeps/unix/sysv/linux/i386/sysdep.S (__syscall_error): Define only #ifndef PIC. * Makeconfig (built-program-cmd): New variable. * sunrpc/Makefile (rpcgen-cmd): Use $(built-program-cmd). * time/Makefile (zic-cmd): Likewise. * hurd/Makefile (user-interfaces): Add hurd/exec_startup.

New macro.

(PSEUDO): Use it instead of SYSCALL_PIC_SETUP and jmp syscall_error.
|

only #ifndef PIC.

* Makeconfig (built-program-cmd): New variable.
|
||||
* sunrpc/Makefile (rpcgen-cmd): Use $(built-program-cmd).

* time/Makefile (zic-cmd): Likewise.

* hurd/Makefile (user-interfaces): Add hurd/exec_startup.
|

|
||||
* sunrpc/Makefile (librpcsvc-no-lib-dep): New variable.
|

* extra-lib.mk: If $(lib)-no-lib-dep is defined and MAKELEVEL>0,
|
||||
make `others' rather than `lib-noranlib' depend on the libraries.
