Subject: include/kernel.mk - better search for ARCH
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=120a88b9da6d8d1b7a04d60e1b25b9925d58eb19;p=openwrt%2Fstaging%2Frobimarko.git

include/kernel.mk - better search for ARCH

If "findstring" is used without leading and trailing spaces unexpected matches
may happen. For example consider ARC=arc then "findstring $(ARCH)" will
report a false match with "aarch64".

But "findstring $ARCH " (note trailing space) will correctly skip
matches for both "aarch64" and "aarch64_be".

This patch is built-tested against NetGear WNDR3800.
