We build with gcc-5 because of zimSplit using ofstream.swap method.
Latest version of zimSplit doesn't use it anymore so let's compile
everything with default gcc.
See openzim/zim-tools@a959609839
We also explicitly set the list of package to install per job, so
less packages are installed.
- Disable icuio and layoutex.
- Hardcode UTF8 as charset (we always use utf8 and hardcoding him improve
performances)
- Do not include default utf headers
- Do not use `using namespace icu`
See http://source.icu-project.org/repos/icu/trunk/icu4c/readme.html#RecBuild
for more information about options.
Increment base dependencies version as we are compiling icu differently.
