[PATCH 1/6] sandbox: use CROSS_PKG_CONFIG when compiling sandbox arch code

[Ahmad Fatoum]

sandbox only means that we run under Linux as host operating system
(as opposed to before). It can still be cross compiled and indeed that's
what barebox-tools in OE-core does to build the target tools.

OE-core doesn't yet build barebox for sandbox itself (only the scripts),
but nonetheless, if it did, SDL and libftdi need to be usable with the
cross toolchain, not with the host toolchain, so let's use
CROSS_PKG_CONFIG accordingly.
