# Uses SDK's CC as linker so linked binaries works out of box.
# We have a problem as rust sets LD_LIBRARY_PATH and this will break running host
# binaries (even /bin/sh) in the SDK as they detect a newer glibc from the SDK
# in those paths and we hit symbol errors. We saw particular problems with symbol
# mismatch on ubuntu1804 during development. To avoid this we have an SDK built
# binary which unsets LD_LIBRARY_PATH, which can then call the wrapper script
# where the context is easier to do the env maniupations needed
