#4 Fix parallel build

[Volkov Peter]

Hello. Judy fails to build with parallel make (-j 10 for example, which are quite common at this time) with the following error:

make[2]: Entering directory `/vt/portage/tmp/portage/dev-libs/judy-1.0.4/work/Judy-1.0.4/doc'

I have reported my 3 patches here today and notice this ticket also exists in the same areas I have been working.
I am unable to access the gentoo patch at this time.
If someone reads this maybe this is of some help to them in the future.

My version of this fix is up at:
https://github.com/dlmiles/libjudy/commit/fb71440179e4ac794b589d37d3825f9f8422d315

This has also be attached to sourceforge judy project Ticket#6 as file 0002:

doc/Makefile.am: mkdir -p man/man3 and parallel building in CI

This corrects the dependency graph:
* so the directory man/man3 is created automatically before being
used as an output directory
* building parallel targets works as expected for symlink generation
