Build step output is truncated

One of my build steps is a buildroot ( build. Since it compiles a cross compilation toolchain and entire linux userland there is quite a lot of output. It seems the output is truncated or wraps around when run as a drone build step. When downloading the buildroot build step output I only get the last 60k (80k through 140k) numbered lines or so. Is there an option to increase the build step output buffer size?
