pip_import/pip_install doesn't support cross-compilation

[jkammerl]

@mhlopko: pip_import/pip_install generates corresponding wheel packages that are always compiled for the host system architecture. Any cross-compilation toolchain specified within the CROSSTOOL configuration is ignored. It would be great if the selected CC compiler from CROSSTOOL could be set before executing "pip install".

Just running into the same issue, building a distroless image that includes pillow-simd from my ubuntu 16.04 machine seems to be quite difficult, especially due to the differences in libjpeg and libwebp libraries. Would there be any possible workarounds for now, apart from using a different base images?
