Subject: devel/strace: fix build on mpc85xx target
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=519a199cbcc0930e229ddd7087309326a846bdce;p=openwrt%2Fstaging%2Flynxis.git

devel/strace: fix build on mpc85xx target

builbot faillog:
https://downloads.lede-project.org/snapshots/faillogs/powerpc_8540/base/strace/compile.txt

Seems that for PPC, the <linux/ptrace.h> header [from uapi] collides
with musl's <sys/user.h>, for the pt_regs struct.

Seems I tried to upstream this patch a while back:
https://lists.openwrt.org/pipermail/openwrt-devel/2016-April/041093.html

It seems to work on current LEDE trunk too.
