Alvaro Herrera 736c95ca16 nls-global.mk: search build dir for source files, too
In VPATH builds, the build directory was not being searched for files in
GETTEXT_FILES, leading to failure to construct the .pot files.  This has
bit me all along, but never hard enough to get it fixed; I suppose not a
lot of people uses VPATH and NLS-enabled builds, and those that do,
don't do "make update-po" often.

This is a longstanding problem, so backpatch all the way back.

# src/nls-global.mk
# Common rules for Native Language Support (NLS)
#
# If some subdirectory of the source tree wants to provide NLS, it
# needs to contain a file 'nls.mk' with the following make variable
# assignments:
#
# CATALOG_NAME -- name of the message catalog (xxx.po); probably
# name of the program
# AVAIL_LANGUAGES -- list of languages that are provided/supported
# GETTEXT_FILES -- list of source files that contain message strings
# GETTEXT_TRIGGERS -- (optional) list of functions that contain
# translatable strings
# GETTEXT_FLAGS -- (optional) list of gettext --flag arguments to mark
# function arguments that contain C format strings
# (functions must be listed in TRIGGERS and FLAGS)
#
# That's all, the rest is done here, if --enable-nls was specified.
#
# The only user-visible targets here are 'init-po', to make an initial
# "blank" catalog from program sources, and 'update-po', which is to
# be called if the messages in the program source have changed, in
# order to merge the changes into the existing .po files.
# existence checked by Makefile.global; otherwise we won't get here
include $(srcdir)/nls.mk
# If user specified the languages he wants in --enable-nls=LANGUAGES,
# filter out the rest. Else use all available ones.
