Public bug reported:

libsdl1.2 fails to build in trusty-proposed due to eglibc 2.18, which
rearranges headers and exposes an incompatibility between eglibc and
kernel handling of P_ALL, P_PID, P_GID.

libtool: compile:  gcc -g -O2 -fstack-protector --param=ssp-buffer-size=4 -Wformat -Werror=format-security -D_FORTIFY_SOURCE=2 -Iinclude -I../../include -D_GNU_SOURCE=1 -fvisibility=hidden -maltivec -D_REENTRANT -DXTHREADS -I/usr/include/ -D_REENTRANT -DHAVE_LINUX_VERSION_H -Wall -c ../../src/video/fbcon/SDL_fbevents.c  -fPIC -DPIC -o build/.libs/SDL_fbevents.o
In file included from /usr/include/linux/keyboard.h:4:0,
                 from ../../src/video/fbcon/SDL_fbevents.c:41:
/usr/include/powerpc64le-linux-gnu/bits/waitflags.h:45:3: error: expected identifier before numeric constant
   P_ALL,  /* Wait for any child.  */
   ^
make[2]: *** [build/SDL_fbevents.lo] Error 1

ppc64el.libsdl1.2_1.2.15-5ubuntu3_FAILEDTOBUILD.txt.gz)

/usr/include/linux/wait.h has P_ALL as a #define; bits/waitflags.h has
it as an enum.  This means one gets compile failures based on the order
of header includes.

The linux header should probably be mixed to match the libc API.
