[Ryan Arnold]

The Linaro Binary Toolchain
============================

The Linaro GCC 5.4-2017.01-rc2 Release-Candidate is now available.

Notice: All Linaro GCC 5 series toolchain users should migrate to the
latest version of the Linaro GCC 5 toolchain in order to mitigate
potential security exposure to CVE-2015-7547. See the NEWS section
below for details.

Host Requirements
==================

Linaro officially supports the current and previous Ubuntu LTS
releases (as of the time of this release). This does not mean that
the toolchain will not work on other/older Linux distributions. See
the following for the life-time of Ubuntu LTS releases.

https://wiki.ubuntu.com/Releases

The host system upon which the cross-compiler will run requires a
minimum of glibc 2.14, because of API changes to glibc's memcpy API.
