ld.so symbols to be overriden by libc need to be extern to really get overriden. * sysdeps/mach/hurd/dl-unistd.h (__access, __brk, __lseek, __read, __sbrk): Do not set attribute_hidden. * sysdeps/mach/hurd/i386/ld.abilist: Update accordingly. * sysdeps/mach/hurd/i386/localplt.data: Update accordingly.
