Subject: build: add -Wno-error=unused-result to target cflags
X-Git-Tag: reboot~1585
X-Git-Url: http://git.openwrt.org/?p=openwrt%2Fopenwrt.git;a=commitdiff_plain;h=940bc81bc2dee35f01c7ca6e5e588f62a20b82f8;hp=b613c96d94bcdcda7abb3be68ea1c281ce5fbb47

build: add -Wno-error=unused-result to target cflags

Many glibc functions have __warn_unused_result__ in so many different
core functions, and failing the build for all of those simply does not
make any sense
