Bug#837492: grub: FTBFS with bindnow and PIE enabled

[Balint Reczey]

Source: grub
Version: 0.97-71
Severity: important
User: balint at balintreczey.hu
Usertags: pie-bindnow-20160906
Justification: FTBFS on amd64 with extra hardening

Hi,

During a rebuild of all packages in sid, your package failed to build on
amd64 with patched GCC and dpkg.

The rebuild tested if packages are ready for a transition
enabling PIE and bindnow for amd64.

For more information about the changes to sid's dpkg and GCC please
visit:

Relevant part (hopefully):
...
checking if C symbols get an underscore after compilation... no
checking whether objcopy works for absolute addresses... no
configure: error: GRUB requires a working absolute objcopy; upgrade your
binutils
        "tail -v -n +0 config.log"
==> config.log <==
This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.

It was created by GRUB configure 0.97, which was
generated by GNU Autoconf 2.69.  Invocation command line was

  $ ./configure --build=x86_64-linux-gnu --prefix=/usr
--includedir=${prefix}/include --mandir=${prefix}/share/man
--infodir=${prefix}/share/info --sysconfdir=/etc --localstatedir=/var
--disable-silent-rules --libdir=${prefix}/lib/x86_64-linux-gnu
--libexecdir=${prefix}/lib/x86_64-linux-gnu --disable-maintainer-mode
--disable-dependency-tracking --libdir=${prefix}/lib
--disable-auto-linux-mem-opt

Thanks,
