It seems flex is required to build gcc:

| .../work-shared/gcc-7.2.0-r0/gcc-7.2.0/missing: line 81: flex: command not found
| WARNING: 'flex' is missing on your system.
|          You should only need it if you modified a '.l' file.
|          You may want to install the Fast Lexical Analyzer package:
|          <http://flex.sourceforge.net/>
| Makefile:2799: recipe for target 'gengtype-lex.c' failed
| make[1]: [gengtype-lex.c] Error 127 (ignored)

Normally this is handled indirectly throught binutils-cross dependency
pulling in flex-native implicitly. For deterministic builds, this should
be specified explicitly.

Oh, this is against rocko, which should be fine for RFC, but I'll rebase for 
master soon...
