Operating System (available in the Info Center app, or by running `kinfo` in a
terminal window): NixOS `i686-linux` target
ADDITIONAL INFORMATION
`x86_64-linux` builds and passes tests without problems. It looks like a recent
none/tests/x86/fb_test_i386.c test has troubles building by `i686` toolchain.
