since commit 0c8dd6ebd656e06cf99a63eb93343715f4853503:

/nvmedata/autobuild/instance-15/output-1/host/lib/gcc/armeb-buildroot-linux-uclibcgnueabi/10.3.0/../../../../armeb-buildroot-linux-uclibcgnueabi/bin/ld: /nvmedata/autobuild/instance-15/output-1/build/dhcp-4.4.3/bind/bind-9.11.36/lib/isc/.libs/libisc.so: undefined reference to `_Unwind_GetIP'
