[CM] linux, sbcl, osc patch

[Fernando Lopez-Lezcano]

I had to add this patch to osc-1.0.1 for it to work (well, don't really
know if it works, not completely tested) on linux/sbcl. 

This was due to a bug report from Joakim in the Planet CCRMA list:

I don't know why the in-package sb-alien is not doing its job. 
As is, the functions following the in-package cm are defined in the 
sb-alien package. Prefixing the alien functions and removing the 
in-package sb-alien make the call work.
