X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=16ac5c4fbd183398d6a1595f6c87fd85c8668b33;p=openwrt%2Fstaging%2Fblocktrron.git

perf: simplify the build process

Redirect the build output to PKG_BUILD_DIR instead of copying over
complete source code.

Build tested on following targets:

 x86/64 ar7/generic ipq40xx/generic imx6/generic ar71xx/generic
 ramips/mt7621 ramips/mt7620 sunxi/cortexa7

Run tested on imx6/apalis.
