* Use descriptions of libraries from the pkg-config file generation function
* Use "FFmpeg Project" as CompanyName (suggested by Alexander Strasser)
* Use "FFmpeg" for ProductName as MSDN says "name of the product with which the
  file is distributed" [1].
* Use FFmpeg's version (N-xxxxx-gxxxxxxx) for ProductVersion per MSDN [1].
* Only build the .rc files when --enable-small is not enabled.

The mmxext optimizations should be at least equally fast if available and
amd3dnow optimizations are being deprecated. Thus the former should
override the latter, not the other way around.

Simplifies host/target libc detection splitting.

Fix leak.

The CONFIG_ name-space is set by configure, so its better to use a
different prefix here.

This makes the USE_FLOATS == 0 available to the end user
More float optimizations can easily be added as well now
common code should be factored out into a common file once all
fixed point & floating point optimizations are done, this is to
avoid having to move code back and forth between files.
