This allows to clean the doc directory from the parent project dir.
The command:
make -C doc clean
does not work as long as the paths specified in doc/Makefile are relative
to the parent dir.
Also it is consitent with "testclean" and "distclean" targets.
Documentation includes only the externally visible API of the installed
headers.

Allow to select specific documentation components, and reliably check for
component dependencies.
In particular, check for perl presence on the system.
The $(dir) function used to construct OBJDIRS includes a trailing slash
in the names returned, which GNU make 3.82 does not match to the
slash-less 'doc' in the documentation dependencies, causing parallel
build to fail. Adding a slash fixes this and still works with make
3.81.

Now that a documentation generator is built in the doc directory,
this is no longer necessary. Fixes the Make warning:
Makefile:188: target `doc' given more than once in the same rule.
When generating the .dep files for .texi sources, verbatim includes
(@verbatiminclude) should also be taken into account.

Setting SRC_PATH to "." when building in-tree removes the need
for a quoted version of the source path since out-of-tree builds
are not possible if the pathname contains spaces.

out of tree builds from a source dir with spaces is impossible
due to how make handles vpath
