new codegen and ccache doesn't work together

[floooh]

• switch on ccache: './fips set ccache on'
• set a ninja or make config: './fips set config osx-ninja-release'
• clean: './fips clean all'
• build: './fips build'

Compile errors because the generator target hasn't been rerun.

Is this because the generated sources are outside the source tree? Didn't this work before but didn't fail because the generated sources were existed (but in the previous version)?

Problem seems to be that the ALL_GENERATE target isn't run before the actual targets which contain code generation files.

hmm, 'ccache -c' after a './fips clean' to clear the ccache cache helps, but kinda defeats the purpose of ccache...
