Latest openwrt git cant build (08.08.2018, ucert - libjson-c.so)

[sfx2000]

dirclean, distclean, and even reclone the repository... my guess it is not an unclean tree...

synced up to head this morning...

make V=s 2>&1 | tee build.log | grep -i error

I just did a make dirclean before build, and I still run into the error if there is no key-build.ucert* in the buildroot dir. If the cert is there, then the build completes (but the log shows an error, even then, but that is not fatal).

Was able to reproduce the issue in an Ubuntu 18.04.1 VM - it should be fixed with https://git.openwrt.org/?p=openwrt/openwrt.git;a=commitdiff;h=5762efd8b29d68e219fc9d00b681269727cbf5d5

A manual make package/libubox/host/{clean,compile} might be needed but I didn't check thoroughly.
