Preserve toolchain sysroot lib's directory structure on target

When building buildroot with Linaro 2013.07 (configured as external or custom
tool), the target would fail to come up, with error:

/sbin/init: error while loading shared libraries: libc.so.6: cannot open shared
object file: No such file or directory

The reason is that starting with Linaro 2013.07, they switched to eglibc-2.17
with multi-arch support. Arch-specific libraries, including libc.so.6, are
expected to be in /lib/arm-linux-gnueabihf/ instead of just /lib. However,
copy_toolchain_lib_root() in helper.mk would end up copying them to /lib rather
than arch-specific directories.

Attached is my own patch to preserve the toolchain sysroot's lib directory
structure, except for SUPPORT_LIB_DIR which are still copied directly under
DESTDIR.

I am having the same issue with the current master of buildroot-git. When
building binaries with the linaro toolchain, generated binaries expect
libc.so.6 to be in /lib/arm-linux-gnueabihf/ but they are only copied to /lib .
A simple symlink also resolves the issue, but I argue with myself if this is
correct...

This has now been fixed in the latest master by adding a symlink in /lib.
Another fix was needed to create a symlink in /usr/lib, and this patch is
pending in the for-peter-2013.11 branch. Marking this bug as fixed.
