Mark __libc_multiple_libcs with attribute_hidden [BZ #18822]
Since __libc_multiple_libcs is defined as hidden symbol in init-first.c, it should be always marked with attribute_hidden. [BZ #18822] * csu/libc-start.c (__libc_multiple_libcs): Removed. * elf/dl-open.c: Include <libc-internal.h>. (__libc_multiple_libcs): Removed. * elf/dl-sysdep.c: Include <libc-internal.h> instead of <hp-timing.h>. * include/libc-internal.h (__libc_multiple_libcs): New. * misc/sbrk.c: Include <libc-internal.h>. (__libc_multiple_libcs): Removed.
