[ptxdist] [PATCH] fix toolchain build with active icecc

[Lucas Stach <dev@lynxeye.de>]

From: Lucas Stach <l.stach@pengutronix.de>

For toolchain builds to work when icecc is activated
we still need to create the host environment, otherwise
we provide an empty ICECC_VERSION and hilarity ensues.

As we don't have a selected_toolchain in this case,
simply check if we already have a packaged env, otherwise
create one.

Signed-off-by: Lucas Stach <l.stach@pengutronix.de>

For now I only checked that the build finishes
successfully with this patch, but didn't check if the
resulting toolchain works correctly.
