-crossdev is using new layout of /etc/portage/package.* . If you don't migrated to this layout yet then you should to it now. New layout is expecting /etc/portage/package.keywords/ (and all others) to be a directory and configuration in files inside of it. For example for AVR target you can find cross-avr there.

 Cross compile is name of build process which produce machine code for different architecture. For example I am also embed device developer and I produce machine code for AVR platform on x86_64 workstation. Effectively I am doing cross compile on x86_64 to AVR target. I am writing source code in C language and partly in assembler.
 == Why sys-devel/crossdev ? ==
-Because it is Gentoo specific tool to manage necessary software to perform cross compile (e.g. binutils, headers, libraries, and compiler). It is very simple to use and save time.
