Split version files into one line per symbol/directive to allow compatibility
with the Solaris linker without preprocessing and eliminate $ from version file
templates to simplify the postprocessing shell command.

These warnings conflict with system macros on Solaris, producing
truckloads of warnings about macro redefinition.

<greyscale sample> <alpha sample> <greyscale sample> <alpha sample>

and the range of multimedia applications is dubious. Thus it only represents
a maintenance burden.

Instead of setting FFLIBS in each library Makefile configure
exports FFLIBS-$library in config.mak.

Prevent a division by zero down the codepath.
