    toolchain: glibc: Fix build with autoconf 2.71
    
    The glibc build was failing with this error message:
      aclocal.m4:6: error: Exactly version 2.69 of Autoconf is required but you have 2.71
      aclocal.m4:6: the top level
    
    The autoconf run on glibc is not needed, just remove it.
    
    Fixes: #12631
    Fixes: 030447b8f4c7 ("tools/autoconf: bump to 2.71")
