ncurses 6.0 - patch
20151101
+ amend change for pkg-config which allows build of pc-files when no
valid pkg-config library directory was configured to suppress the
actual install if it is not overridden to a valid directory at
install time (cf:
20150822).
+ modify editing script which generates resulting.map to work with the
clang configuration on recent FreeBSD, which gives an error on an
empty "local" section.
+ fix a spurious "(Part)" message in test/ncurses.c b/B tests due
to incorrect attribute-masking.
