[Buildroot] [PATCHv2 00/10] toolchain: improvements to copy_toolchain_sysroot and copy_toolchain_lib_root

[Thomas De Schampheleire <patrickdepinguin@gmail.com>]

From: Thomas De Schampheleire <thomas.de_schampheleire@nokia.com>

Hi,

This toolchain patch series started out to fix the handling of the Cavium Octeon
2 toolchain (see patch "cover multilib toolchains with lib/<variant>/layout")
but along the way I fixed/improved a few other things.
Details are found in the commit messages of these patches.

I tested a number of external toolchains and arches available in Buildroot, as
well as the Octeon SDK toolchain.  I think I understand the situation
sufficiently well to get some confidence, but this is the type of
change that is difficult to get 100% certainty about.

Best regards,
Thomas
