Fix missing library entries for Linaro toolchain

Not all Linaro toolchains were set up properly.

This causes a panic

Freeing unused kernel memory: 372K (806e1000 - 8073e000)
/sbin/init: error while loading shared libraries: libc.so.6: cannot open shared object file: No such file or direy
Kernel panic - not syncing: Attempted to kill init! exitcode=0x00007f00

Fix by setting up some library symlinks
