Initial Package Version: 2.5
Upstream Status: Not sent
Origin: Hugo Villeneuve
Description: Fix the following compilation error:
  /bin/sh ../../../libtool --tag=CXX   --mode=link g++ -I../../../include -I
    -pipe -O2 -march=native -fomit-frame-pointer -version-info 2:4:0  -L  -o
    libaggplatformX11.la -rpath /usr/local/lib
    libaggplatformX11_la-agg_platform_support.lo -lX11
  libtool: link: require no space between `-L' and `-o'

This is caused by an empty variable x_libraries. Added a conditional automake
variable to prevent that.
