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

[Yann E. MORIN <yann.morin.1998@free.fr>]

Romain, All,

On 2016-10-29 14:08 +0200, Romain Naour spake thusly:
> 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.

Again, for consistency with other functions/macros, it would have been
nice to introduce a local variable.
