Trying to get correct version of pymavlink (i.e. the one with messages
references in our mavlink repository)
As-is, if there is a pymavlink release after the one references in the
ardupilot repo, we don't pick up any new messages in the Python
bindings.
Remove old CMake PPA (Trusty has a more recent version)
Remove ccache from APT install since we build it from source
Update ccache to version 3.4.2
Add extra checks for compiler presence
Since no ccache DB is saved between builds we don't limit its size anymore and Make builds can use it
Update ccache to 3.2.5
Set ccache size
Display ccache statistics for each build
Disable ccache for configure phase
Export ccache bin path
travis: remove ccache stats before saving cache
PX4 isn't supported at the moment and sitltest always use GCC, so we include the only ones that build
Travis has old LLVM installed and old Clang in a strange path (not a package) which interfere with the use of clang-3.7
