  Fix runtime error with uClibc
  
  Patch inspired by
  https://www.winehq.org/pipermail/wine-bugs/2011-September/288987.html
  http://git.alpinelinux.org/cgit/aports/tree/main/wine/uclibc-fmaxf-fminf.patch?id=c9b491b6099eec02a835ffd05539b5c783c6c43a
  
  Starting an app using mesa3d 10.5.x, Kodi for example, fails:
  
  /usr/lib/kodi/kodi.bin: symbol 'fminf': can't resolve symbol in lib '/usr/lib/dri/i965_dri.so'.
  libGL error: unable to load driver: i965_dri.so
  libGL error: driver pointer missing
  libGL error: failed to load driver: i965
  libGL error: unable to load driver: swrast_dri.so
  libGL error: failed to load driver: swrast
  
  This patch was rejected by upstream mesa3d:
  http://lists.freedesktop.org/archives/mesa-dev/2015-March/079436.html
  
  The real fix was committed to uClibc:
  http://git.uclibc.org/uClibc/commit/?id=6c4538905e65ceb203f59aaa9a61728e81c6bc0a
  
  Until the external toolchains do not contain this uClibc patch we keep this
