[Buildroot] [PATCH 03/30] toolchain-external: pass arguments CROSS to install wrapper

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

As soon as the external toolchain infrastructure gets introduced in a
future commit, the TOOLCHAIN_EXTERNAL_CROSS will be provided by the
external toolchain package using <external-toolchain-name>_CROSS.

This commit prepares the transition to the external toolchain
infrastructure by passing CROSS as function arguments.
