It may be possible to solve this problem by using package.mask to
prevent one of those packages from being selected. However, it is also
possible that conflicting dependencies exist such that they are
impossible to satisfy simultaneously.  If such a conflict exists in
the dependencies of two different packages, then those packages can
not be installed simultaneously.

For more information, see MASKED PACKAGES section in the emerge man
page or refer to the Gentoo Handbook.

Use --autounmask-write to write changes to config files (honoring
CONFIG_PROTECT). Carefully examine the list of proposed changes,
paying special attention to mask or keyword changes that may expose
experimental or unstable packages.

 * In order to avoid wasting time, backtracking has terminated early
 * due to the above autounmask change(s). The --autounmask-backtrack=y
 * option can be used to force further backtracking, but there is no
 * guarantee that it will produce a solution.

!!! The following installed packages are masked:

# These old versions of toolchain packages (binutils, gcc, glibc) are no
# longer officially supported and are not suitable for general use. Using
# these packages can result in build failures (and possible breakage) for
# many packages, and may leave your system vulnerable to known security
# exploits.
# If you still use one of these old toolchain packages, please upgrade (and
# switch the compiler / the binutils) ASAP. If you need them for a specific
# (isolated) use case, feel free to unmask them on your system.

# Andreas K. Huettel <dilfridge@gentoo.org> (27 May 2017)
# In the 17.0 profiles we assume that our system compiler uses C++14
# or later as default language setting. This means it has to be at
# least GCC 6. If you need an older compiler for specific purposes,
# feel free to unmask it, however, using it for normal emerging of
# packages is neither recommended nor supported in any way.
