Diego Biurrun 14cab426b0 build: Hardcode avversion.h dependency
Since avversion.h is a generated header it must be created before
dependencies can be determined as a side effect of compilation.
Otherwise Make stops and restarts the build process to generate
avversion.h and produces related error messages.

Diego Biurrun 535a742c26 build: Change structure of the linker version script templates
Split version files into one line per symbol/directive to allow compatibility
with the Solaris linker without preprocessing and eliminate $ from version file

Sean McGovern c1aac39eac build: add Solaris symbol versioning
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.

wm4 1316df7aa9 lavu: add an API function to return the Libav version string
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.
