Subject: [PATCH] [configure.in] Add paranoid double checking for (svg|pdf)2png

Due to my incomplete cross-build environment, configure detects the
presence of rsvg and poppler, but they cannot be used. To make my life
easier, add a check similar to that used for fontconfig to ensure the
libraries are usable before compiling the optional test utilites.
