To be honest, this sounds like a packaging issue.
libcc1.so should not be installed by a specific cross compiler at all,
at least not for the host architecture and certainly not into /usr/lib.

If the libcc1 versions used by gcc-avr and/or gcc-sh-elf are
incompatible with what's provided by libcc1-0, then these two packages
should either be linked statically or their own versions be installed
into /usr/lib/<package-name>/lib (or something similar)

FWIW, this is likely caused by these two cross compilers being based on
very old gcc versions.

At least gcc-avr should be fixed by upgrading it to something newer than
the Atmel/Microchip-patched version.
