Hi Matthias,

  Thanks for reporting this.

  It looks to me is the same issue reported here?

    https://sourceware.org/ml/binutils/2017-06/msg00226.html

  I guess ld.so actually have not been built successfully.  You may need to
redirect the build log to a text file then search that error, somehow glibc
build won't stop even that error happens.

  I could reproduce this issue on AArch64, and could confirm it's fixed after
backporting the following fix from master branch to 2.24.

  could you please confirm the backport works for you as well?
