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.

The problem here is that you are using --with-build-sysroot but not
--with-sysroot.  --with-sysroot enables support for sysroots.
--with-build-sysroot changes the sysroot value used during the build,
but does not itself enable sysroot support.  So using
--with-build-sysroot without --with-sysroot is useless.  This is
mentioned in the install docs.  You can specify --with-sysroot=/ to
enable sysroot support, without specifying an alternative host sysroot
dir.  That makes the build succeed.

I think the --includedir option here is useless.  includedir is
supposed to be for the dir where gcc header files are installed, which
is not /usr/include, but rather $prefix/include.  This should not be
necesary but appears to be harmless.
