The Musl C library only supports Microblaze BE, not Microblaze LE, so
this commit adjusts the dependencies of the toolchain-buildroot
package to not allow the selection of Musl on Microblaze LE.

This enables powerpc64 and powerpc64le. Currently, le needs at least
glibc 2.19 and gcc 4.9.0. For gdb, 7.7.1 works (added in an earlier
patch).
[Peter: also disallow gcc 4.8 for ppc64le]

This patch adds support for powerpc64le-linux-gnu. This includes
needed patches to fakeroot and gmp.
gmp patch is from upstream HG tree.
fakeroot patch is from Ubuntu written by Adam Conrad.

This option allows to customize the "vendor" part of the
toolchain tuple, where the toolchain tuple has the form
<arch>-<vendor>-<os>-<libc>. Use this option in situations
where gcc might make different decisions based on the vendor
part of the tuple.
[Thomas: move the config option in a slightly different place, so that
it does not appear between the C library selection and the C library
options.]

glibc 2.19 has been released recently
(https://sourceware.org/ml/libc-alpha/2014-02/msg00224.html). This
commit allows to build a toolchain with this new version. In order to
allow this, we add a version selection that did not exist for
glibc. We default to 2.18, which was the only supported version until
now, and add an option for 2.19.
For microblaze, which uses a specific glibc version, the version
selection choice is not displayed.

This commit allows to build an internal toolchain for the Microblaze
architecture, with either glibc or eglibc.
Note that we add an explicit list of architectures that are supported
by uClibc, and Microblaze is not part of them, because it currently
doesn't build for this architecture.
[Thomas: add better commit log, add architecture dependencies on
uClibc, to avoid selecting uClibc on Microblaze]

(e)glibc doesn't support a fully statically linked userspace. Even a
basic program such as Busybox fails to do authentication due to glibc
loading some libraries dynamically. Therefore, we disable the
possibility of building a glibc toolchain when
BR2_PREFER_STATIC_LIB=y.

The only remaining thing in toolchain-buildroot/Config.in.2 is the
inclusion of the elf2flt option. It doesn't really make sense to have
a separate Config.in file for that, so let's move this to
toolchain-buildroot/Config.in.

The support for eglibc 2.17 was added to the internal toolchain
backend for 2013.08. This commit now adds glibc 2.18 support to the
internal toolchain backend.
Since the building procedure is very similar to the one of eglibc, we
have renamed the 'eglibc' package to 'glibc', and made it capable of
handling either glibc or eglibc.

Using the newly introduced 'eglibc' package, this commit enables the
option of building a toolchain using the eglibc C library in the
Buildroot toolchain backend.
In details, this commit:
* Creates a choice to select uClibc or eglibc in the Buildroot
toolchain backend (in toolchain/toolchain-buildroot/Config.in), and
removes the fact that the Buildroot toolchain backend forcefully
enables uClibc (toolchain/Config.in).
* Creates a BUILDROOT_LIBC variables, which points to the package
implementing the C library (i.e either 'uclibc' or 'eglibc').
* Modifies the gcc-final and gcc-intermediate makefiles to use the
BUILDROOT_LIBC variable instead of hardcoding the use of uclibc.
* Ensures that TLS support is always enabled when building eglibc.
[Peter: fix commit text to refer to BUILDROOT_LIBC]

* Build tools are on HOST_DIR now so change it
* Move cross/host gcc to HOST_DIR
* Drop kludge from commit 3c77bab2ee

target compilations.
