don't skip cleanup

[jaakkor2]

Try to remove interference between the platform builds, could help for JuliaGeo/LibGEOS.jl#56

[jaakkor2]

Close for now

Thanks for thinking along! Has this been a problem for other Builders as well? The reason the new GEOS build is not working on Win64 now is also reported here: JuliaPackaging/BinaryBuilder.jl#407.

I was planning to test make clean as well, but I could not get Travis to generate binaries for my fork. Would trying only Win64 build make sense?

Yes you can run only the Win64 build. I don't think the reason for the issues is contamination between the environments, but rather issues with mixing compiler versions. We could for instance try to split out the GCC versions in the GEOSBuilder, and try using GCC7, like in JuliaPackaging/BinaryProvider.jl#152

For development it is also convenient to build locally on Linux, with

julia --color=yes build_tarballs.jl --verbose --debug x86_64-w64-mingw32
