binutils: patch 2.16 for uclibc, enable 2.16 on uclibc builds
2.16 now includes the patches which ensure that HOST_CC_ARCH is passed to
the build, other than that this commit should only affect binutils for
linux-uclibc targets.  The patches which enable recognition of
linux-uclibc*' as well as 'linux-gnu*' have integrated - in fact there are
more places now where the change is made, which may improve some things.
The apparently spurious 'autoreconf' of certain subdirectories in the build
tree has been commented out (it did nothing because there is no configure.in
or .am in the build directory).
