Yes, there is: Download the source of the module and look at it.  C 
code is visually very different from Lua code.  Moreover, lua source 
code usually is in files with the extension .lua.

You don't need to do that either.  If by inspection of the source you 
determine that it contains some C code, you can try to compile the 
module and see if it builds.  You'll be needing to do this for any 
module which contains C anyway, since most authors have never heard of 
Blackfin and certainly don't have the opportunity to compile their 
module for you.
