Bug: faulty links in /lib/modules/5.12.9-1-default/

Installation of kernel 5.12.9 resulted in the following links in /lib/modules/5.12.9-1-default/: build -> ../../../usr/src/linux-5.12.9-1-obj/x86_64/default source -> ../../../usr/src/linux-5.12.9-1 In each case, the target should be the absolute path /usr/src/.... not the relative path given. This bug prevents the building of external modules such as the nvidia drivers. The problem was also present for kernel 5.12.4, and probably in older kernels; however, I no longer have any of those on my system. This is reported as boo#1186899. Larry
