62# @DEFAULT_UNSET
63# @DESCRIPTION:
64# If defined this variable contains a whitelist of shared objects that
65# are allowed to exist even if they don't link to libruby. This avoids
66# the QA check that makes this mandatory. This is most likely not what
67# you are looking for if you get the related "Missing links" QA warning,
68# since the proper fix is almost always to make sure the shared object
69# is linked against libruby. There are cases were this is not the case
70# and the shared object is generic code to be used in some other way
71# (e.g. selenium's firefox driver extension). When set this argument is
72# passed to "grep -E" to remove reporting of these shared objects.
