[pve-devel] [PATCH docs 1/4] pve-doc-generator: make include dirs configurable

[Fabian Grünbichler]

by setting PERL_DOC_INC_DIRS before including pve-doc-generator.mk

Signed-off-by: Fabian Grünbichler <f.gruenbichler at proxmox.com>

note: needed by pve-manager, pve-cluster could probably also use this. future
changes moving doc-generation into its own subdir/makefile would also benefit
from having this already in place ;)
