Remove INTDEF / INTUSE / INTVARDEF (bug 14132).
Completing the removal of the obsolete INTDEF / INTUSE mechanism, this patch removes the final use - that for _dl_starting_up - replacing it by rtld_hidden_def / rtld_hidden_proto. Having removed the last use, the mechanism itself is also removed. Tested for x86_64 that installed stripped shared libraries are unchanged by the patch. (This is not much of a test since this variable is only defined and used in the !HAVE_INLINED_SYSCALLS case.) [BZ #14132] * include/libc-symbols.h (INTUSE): Remove macro. (INTDEF): Likewise. (INTVARDEF): Likewise. (_INTVARDEF): Likewise. (INTDEF2): Likewise. (INTVARDEF2): Likewise. * elf/rtld.c [!HAVE_INLINED_SYSCALLS] (_dl_starting_up): Use rtld_hidden_def instead of INTVARDEF. * sysdeps/generic/ldsodefs.h [IS_IN_rtld] (_dl_starting_up_internal): Remove declaration. (_dl_starting_up): Use rtld_hidden_proto. * elf/dl-init.c [!HAVE_INLINED_SYSCALLS] (_dl_starting_up): Remove declaration. [!HAVE_INLINED_SYSCALLS] (_dl_starting_up_internal): Likewise. (_dl_init) [!HAVE_INLINED_SYSCALLS]: Don't use INTUSE with _dl_starting_up. * elf/dl-writev.h (_dl_writev): Likewise. * sysdeps/powerpc/powerpc64/dl-machine.h [!HAVE_INLINED_SYSCALLS] (DL_STARTING_UP_DEF): Use __GI__dl_starting_up instead of _dl_starting_up_internal.
