X-Git-Tag: v19.07.0-rc1~2283
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=4d2613b01ac6d34c2de550472ad9167e28ebd11e;p=openwrt%2Fstaging%2Fhauke.git

mpc85xx: workaround 4.14 cross compile issue

Regression introduced with 4.10 by 43c9127d94d62a232ed33ed2eab8a08657ce5472

Build will fail if system 'ar' does not support deterministic builds.
e.g. macOS with Xcode toolchain

Appears to be fixed upstream in 4.18 by af3901cbbd3de182aafb8ee553c825c0074df6a2
