Bug description:
  Binary package hint: gcc-4.4

  Hi

  Since it's built with gcc-4.4, eglibc isn't PIC anymore; just like
  almost all shared objects we built.

  Debian noticed this issue when considering the gcc-4.4 switch:
  http://lists.debian.org/debian-arm/2009/09/msg00062.html
  and the eglibc testsuite has test check-textrel.out which fails since it's not PIC anymore.

  The issue is in gcc-4.4 which generates the wrong type of ELF data for
  exception handling (eh_frame).

  This prompts for a rebuild of a bunch of packages between beta and
  final with a fixed toolchain.

  A workaround is to build things with -fno-dwarf2-cfi-asm.  We should
  upload eglibc built with this ASAP.

  We should also patch gcc-4.4 to default to setting this flag on ARM EABI:
  http://gcc.gnu.org/ml/gcc-patches/2009-10/msg00071.html
  See also PR40521 which is an issue in gas that prevents the proper fix in gcc.

  We should include this patch in our gcc-4.4 ASAP and rebuild the
  toolchain against it.
