[Bug 1742277] [NEW] FTBFS in bionic

[Eric Desrochers]

Public bug reported:

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 properly build with a hunk FAILED as follow :
