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.
