[Buildroot] [PATCH 5/5] toolchain-external: unify LIB_EXTERNAL_LIBS and USR_LIB_EXTERNAL_LIBS

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

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

With the alignment of toolchain library location in target and staging,
there is no need anymore for the distinction between LIB_EXTERNAL_LIBS and
USR_LIB_EXTERNAL_LIBS. Unify them into TOOLCHAIN_EXTERNAL_LIBS.

Related, update the help text of
BR2_TOOLCHAIN_EXTRA_TOOLCHAIN_EXTERNAL_LIBS.
