build replicant 4.2 under debian
I have to rebuild an old replicant 4.2 version I need to reinstall to make a clean backup before trying to install replicant 6 (this is linked to https://redmine.replicant.us/boards/3/topics/14711 issue).
I followed instructions and here are a few corrections about replicant 4.2 building:
- `./vendor/replicant/build-toolchain` only needed for replicant 6 (I modified the page for all devices, according to history instructions)
- javac (openjdk) needs to be installed in version 1.6 or 1.7 but it is currently 1.8 into debian repo so line 124 of file `build/core/main.mk` needs to be added a `8` in the grep part `'[ "]1\.[\. "$$]'` => in fact, this solution does not work, build finished with an error
- `./vendor/replicant/sign-build i9100` only needed for replicant 6 (I modified the page for all devices, according to history instructions)
