Subject: ipset: size optimizations
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=89c8232f78f4acd982f66bd285f1448bbbad1719;p=openwrt%2Fstaging%2Fxback.git

ipset: size optimizations

ipset utility was linked statically to libipset. Disable static library for dynamic linking to save space.
Add -Wl,--gc-sections,--as-needed for further reduction

MIPS ipk size:
ipset: 29KiB -> 2KiB
libipset: 39KiB -> 38KiB
