[Bug 1261872] Re: P_ALL behavior inconsistent in eglibc vs. kernel headers (enum vs. #define)

[Adam Conrad]

This was worked around in eglibc with some ifdef magic, but we still
need to sync the headers upstream in one way or another.

  P_ALL behavior inconsistent in eglibc vs. kernel headers (enum vs.
  #define)

Bug description:
  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.
