now I get the same error. You can't just uncomment it with '#', because
all followed files will _not_ be added anymore. Just remove the lines
completely. The issue here is that all files are concatenated by the '\'
at the end of each line. If you uncomment one in between, all lines (and
therefore files) below will not be compiled anymore.

In case it is successful, on x86 I get:
readelf -s build/x86_32/core/sel4/core-sel4.o | grep log | grep Log
7729: 00000000 0 NOTYPE GLOBAL DEFAULT UND _ZN6Genode3Log3logEv
Here you see the symbol part of core.o.
