Search path information is used in build environments (guix build),
user-defined environments (guix environment), and profiles (guix
package).  For example, when you run 'guix package --search-paths',
the environment variables printed are determined by the
native-search-paths field for each package in your profile.

I found that without CROSS_CPATH and CROSS_LIBRARY_PATH the compiler
doesn't work because it can't find all of its headers and libraries
since they aren't in /usr.

Some background: avr-gcc was broken for a very long time, until
Manolis, Ricardo, and I worked out the problems several months ago.  I
tested avr-gcc by successfully compiling the various KADE miniArcade
firmwares using the 'make-all.sh' script found here:
https://github.com/kadevice/KADE/tree/master/open%20software/firmwares/KADE%20miniArcade/sources

I don't know what has changed since I got things working, but I can no
longer compile that firmware.  I get errors like this:

    main.c:38:20: fatal error: avr/io.h: No such file or directory
