-Subject: [PATCH] Fix build failure on ppc
-
-ppc/trace.c is using waitstatus bits without including the appropiate
-headers, leading to a build failure:
-
-libtool: link:
-/home/gustavoz/b/test/output/host/usr/bin/powerpc-buildroot-linux-uclibc-gcc
--Wall -Wsign-compare -Wfloat-equal -Wformat-security -pipe -Os -o ltrace
-main.o  ./.libs/libltrace.a -lelf
-./.libs/libltrace.a(lt1-trace.o): In function `syscall_p':
-trace.c:(.text+0x28): undefined reference to `WIFSTOPPED'
-trace.c:(.text+0x40): undefined reference to `WSTOPSIG'
