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

From: Thomas De Schampheleire <thomas.de.schampheleire at gmail.com>

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.
