Subject: build: remove stray empty variable
X-Git-Tag: upstream/1.0.2~38
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=610b551585fa97e76895a68def2bd041c733e20b;p=platform%2Fupstream%2Flibnetfilter_queue.git

build: remove stray empty variable

Compilation can fail when libnfnetlink is not in a directory searched
by default. Reason is the empty KERNELDIR variable which makes for a
gcc command like:

	gcc -I. -I../include -I -Wall -I/usr/include/libnfnetlink-1.0.0+git28
	-Wall -c libnetfilter_queue.c

What one would expect is that gcc would search in the (non-existent)
directory "-Wall" and just continue as usual, since -Wall is specified
again. Instead, gcc versions before 4.6 attempt to search the
(similarly non-existent) directory "-I/usr/[...]" and thus miss.
