Title:
  FTBFS in bionic

Status in cross-toolchain-base package in Ubuntu:
  New

Bug description:
  Debian commit [60fb7e6] in glibc first introduced in
  "debian/2.25-0experimental3-25-g60fb7e6", has the effect to create a
  FTBFS situation for "cross-toolchain-base" on Bionic which uses glibc
  2.26.

  In fact after the above commit, the patch "debian/patches/glibc/ubuntu
  /no-gdb-python-hooks.diff" found in cross-toolchain-base source code
  is no longer needed and can be safely remove as it tries to modify a
  piece of code already in place in glibc introduced by [60fb7e6],
  preventing the package to build with a hunk FAILED as follow :

  # Launchpad buildlog : https://launchpadlibrarian.net/348143571/buildlog_ubuntu-bionic-amd64.cross-toolchain-base_19ubuntu1_BUILDING.txt.gz
