patch-lib-common-shapes.c

Doesn't help:

  $ make
  checking for sincos... no
  [...]
  ../../lib/gvc/.libs/libgvc.so: undefined reference to `sincos'
  cc: error: linker command failed with exit code 1 (use -v to see invocati=
on)
  [...]
  ../../plugin/neato_layout/.libs/libgvplugin_neato_layout.so: undefined
reference to `sincos'
  cc: error: linker command failed with exit code 1 (use -v to see invocati=
on)

I've also tried adding

  # Bug 220590: -ffast-math is broken without sincos in libm
  CFLAGS_armv6=3D -fno-unsafe-math-optimizations

but it doesn't help due to the order of CFLAGS on command line.
