[Buildroot] [PATCH v2 03/23] toolchain-external: TOOLCHAIN_EXTERNAL_INSTALL_WRAPPER: use arguments instead of global variables

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

A new external toolchain package infrastructure will be introduced in a
followup patch, so TOOLCHAIN_EXTERNAL_{CC,CFLAGS...} global variables
will no longer exist. Instead, each external toolchain packages will
provide it's own <toolchain-external-name>_{CC,CFLAGS...} variables.

For the case of the toolchain wrapper install, CROSS is needed when
calling TOOLCHAIN_EXTERNAL_INSTALL_WRAPPER.
