I did a diff of every file in the output before and after dropping
gettext, flex, bison, and python from native-inputs, and barring for the
output's own hash, files were bit-identical.

(I copied the store items to somewhere, ran 'sed -i s/<hash>//' on every
file (via find) for each item with its hash, then did a recursive diff.)

I've been told that Python/mako are used when rebuilding parts of the
build system, which apparently many people do because they frequently
edit some grammar files (hence also bison).


I pushed the patch to core-updates now.
