  # Qt Embedded for Linux
  #
  # This makefile was originally composed by Thomas Lundquist <thomasez@zelow.no>
  # Later heavily modified by buildroot developers
  #
  # BTW, this uses alot of FPU calls and it's pretty slow if you use
  # the kernels FPU emulation so it's better to choose soft float in the
  # buildroot config (and uClibc.config of course, if you have your own.)
