Title:
  ld hangs indefinitely statically linking binutils on ppc64el

Status in binutils:
  Unknown
Status in binutils package in Ubuntu:
  Fix Released

Bug description:
  The latest util-linux upload, 2.27.1-1ubuntu1, reproducibly fails to
  build on ppc64el because the build hangs indefinitely:

  linux/2.27.1-1ubuntu1/+build/8230106

  The hanging command is:

  strace shows it repeatedly calling brk(), so presumably trying to
  allocate more memory in very small increments.

  It doesn't appear to be lto-related.  The symptom is reproducible when
  calling gcc with -fno-lto.

  I do not yet have a useful backtrace from ld for this, because for
  some reason recent versions of binutils are not getting dbgsym
  packages in the archive.
