I remember now updating my recipe to yours but I needed some configuration
tweaks to deal with a few issues:
- /usr/bin/cc is default used as linker but it is sunstudio 12.1 so you
need to override it,
- AR should be specified,
- this recipe assumes that GCC runtime libraries are in /usr/lib/$(MACH64)
which is not true for us with GCC >= 6,
- the linker should be specified for the target as it is not passed from
the global settings.

Also rustc will eat up to 3GB of RAM so the host should have enough memory.
