[yocto] Compiling different version of IGB as a kernel module

[Jonathan Haws]

Got it figured out.  Turns out I needed some more changes to the 
Makefile.  New patch attached in case anyone is interested.

Bottom line is that the CC command was getting forcibly set at some 
point to check compilers, thus overriding the shell setting.  Plus it 
needed a modules_install as well.

Thanks!
