Hm, that is very strange, I've just built those ports successfully, and there
were no linking errors whatsoever?

Gerald, do you have any idea what might cause linking of e.g. gencondmd to fail
with:

c++ -std=gnu++98   -g -DIN_GCC    -fno-strict-aliasing -fno-exceptions
-fno-rtti -fasynchronous-unwind-tables -W -Wall -Wno-narrowing -Wwrite-strings
-Wcast-qual -Wno-format -Wmissing-format-attribute -Woverloaded-virtual
-pedantic -Wno-long-long -Wno-variadic-macros -Wno-overlength-strings
-fno-common  -DHAVE_CONFIG_H -DGENERATOR_FILE -fno-PIE  -no-pie -o

and then a whole bunch of similar "missing" symbols?  Maybe the host is busted
somehow?
