makepkg : fix a lot of breakages caused by Allan

This patch started as a simple typo fix (pugre instead of purge in two
places), as well as a fix of a test which was using PURGE_TARGETS instead of
$PURGE_TARGETS.

It evolved in a slight handling change of the OPTIONS which have a variable
affecting their behavior (strip STRIP_DIRS, docs DOC_DIRS, zipman MAN_DIRS
and purge PURGE_TARGETS), as well as a clarification in makepkg.conf. Now
when a variable is undefined or empty, the corresponding option will have no
effect. It looked weird to have a fallback when a option is defined but
empty, it seems more natural to not have any fallbacks.

Also re-enable docs by default. It seems arbitrary to delete files from
packages by default, and it would be more vanilla and distro agnostic to
keep them. docs was also the only negated option.
