[Buildroot] [PATCH 2/5] toolchain-external: remove unused calculation of ARCH_SUBDIR

[Romain Naour <romain.naour@gmail.com>]

Hi Thomas, all,

> In TOOLCHAIN_EXTERNAL_INSTALL_TARGET_LIBS, ARCH_SUBDIR is calculated but not
> used, and can thus be removed. Since SYSROOT_DIR is only used for the
> calculation of ARCH_SUBDIR, it can be removed too.
