There are still some issues with the flannel build:

  http://autobuild.buildroot.org/results/d98/d98e1857590738313a293b58f02230539bbaa405/build-end.log

The error is:

/home/buildroot/autobuild/run/instance-2/output/host/opt/ext-toolchain/bin/../lib/gcc/arm-buildroot-linux-uclibcgnueabi/4.9.3/../../../../arm-buildroot-linux-uclibcgnueabi/bin/ld: cannot find Scrt1.o: No such file or directory

My understanding is that this happens when trying to build PIE binaries
that are statically linked. uClibc does not support that, or at least
not with our current toolchain support. Would it be possible to not
build PIE binaries with Go ? Or alternatively, investigate if it can be
fixed in uClibc ?

Waldemar, maybe you have some input about this problem ?

Best regards,

Thomas
