Don't use INTDEF/INTUSE with _dl_argv (bug 14132).
Continuing the removal of the obsolete INTDEF / INTUSE mechanism, this patch replaces its use for _dl_argv with rtld_hidden_data_def and rtld_hidden_proto. Some places in .S files that previously used _dl_argv_internal or INTUSE(_dl_argv) now use __GI__dl_argv directly (there are plenty of existing examples of such direct use of __GI_*). A single place in rtld.c previously used _dl_argv without INTUSE, apparently accidentally, while the rtld_hidden_proto mechanism avoids such accidential omissions. As a consequence, this patch *does* change the contents of stripped ld.so. However, the installed stripped shared libraries are identical to those you get if instead of this patch you change that single _dl_argv use to use INTUSE, without any other changes. Tested for x86_64 (testsuite as well as comparison of installed stripped shared libraries as described above). [BZ #14132] * sysdeps/generic/ldsodefs.h (_dl_argv): Use rtld_hidden_proto. [IS_IN_rtld] (_dl_argv_internal): Do not declare. (rtld_progname): Make macro definition unconditional. * elf/rtld.c (_dl_argv): Use rtld_hidden_data_def instead of INTDEF. (dlmopen_doit): Do not use INTUSE with _dl_argv. (dl_main): Likewise. * elf/dl-sysdep.c (_dl_sysdep_start): Likewise. * sysdeps/alpha/dl-machine.h (RTLD_START): Use __GI__dl_argv instead of _dl_argv_internal. * sysdeps/powerpc/powerpc32/dl-start.S (_dl_start_user): Use __GI__dl_argv instead of INTUSE(_dl_argv). * sysdeps/powerpc/powerpc64/dl-machine.h (RTLD_START): Use __GI__dl_argv instead of _dl_argv_internal.
