If links don't work, fall back to using the full source path as was
previously done.

This should fix build failures with MSVC.

Previously the full source path was embedded inconsistently in the debug
information between in-tree/out-of-tree builds.

The 'vpath %.inc' becomes necessary for finding
libavfilter/all_channel_layouts.inc in out-of-tree builds.

The full source path is still embedded in the debug information, but
it's now independent of whether building in-tree or out-of-tree.

The biggest improvement of this patch is that gdb now always searches
for the path relative to the source directory. It still also searches
for the full path.
Previously it searched only for the full path in out-of-tree builds,
making the debug information generated by Debian's buildds rather hard
to use.

The versioning facility in the Solaris linker differs from Linux in 3 ways:

1. It does not support globs in linker scripts for
symbol versioning -- this is a GNU extension.

2. The linker argument is '-M', instead of '--version-script'.

3. It is picky about line endings.
Each symbol or directive must be on a line of it's own.

Let's use make_sunver.pl from GCC to generate a version script that works
correctly with the Solaris linker. It's function is to correctly expand the
globs in the original generated version script.

This returns something like "v12_dev0-1332-g333a27c". This is much more
useful than the individual library versions, of which there are too
many, and which are very hard to map back to releases or git commits.

There are no independant uses of mips32r2 instructions except for the
FPU parts. Due to the heavy use of mips32r2 specifc fpu extensions, I
am guessing the original author intended MIPSFPU to imply MIPS32R2 anyway.

Since these fpu instructions are available on mips64 (non-r2), enable them
there as well.

Also remove the last occurence of HAVE_MIPS32R2 (which is coupled to
HAVE_MIPSFPU anyway).

mips32r2 is left in the list of options form compatability so that using
--disable-mips32r2 doesn't break anything.

The options is useful to build position-independent executables on

* Use "FFmpeg" for ProductName as MSDN says "name of the product with which the

Also the libavutil/ffversion.h will be installed.

Rationale:
* Applications might want to know FFmpeg's version besides the individual
  libraries'.
* Avoids file name clash between FFmpeg's ./version.h and lib*/version.h when
  a library source file includes both and is compiled on an out-of-tree build.
