Conflicts:
	src/lib/acl/tests/Makefile.am

Moved some requirements content. Document log4cplus needed.
Mentioned some other C++ compilers tested.
Some minor changes.

add them for some run_xxx.sh scripts. Otherwise "from source" invocation
or systest would fail.
basically trivial, and okayed on jabber.  directly pushing it.

Probably due to the python ccsession code now needing the log library, nearly every python test failed without that workaround, so a lot of makefiles needed that same workaround

in master the bus error was fixed, but not in this branch. There was no noticeable conflict, but the merge did make it break again (by redefining the InternalError within the anonymous namespace)

if in any of the other paths there was an old log.so, it would choose that otherwise

fixes distcheck failure in src/lib/acl/tests

Auto(conf|make|whatever it is) tracks deps only when the library is
simple filename. It failed because it wanted to create libdnsacl before
libacl, this way it knows it should wait.
