  Subject: [PATCH] gd_bmp: fix build with uClibc
  
  Some architectures (like ARM) don't have the long double variants of math
  functions under uClibc. Add a local ceill definition in this case.
  
  Patch status: reported upstream, 
  https://bitbucket.org/libgd/gd-libgd/issue/123/build-failure-agains-uclibc-arm
