Downstream distributors can use this to mark a version with their
preferred version information, like a Linux distribution package version
or the Steam revision it was built to be bundled into, or just to mark
it with the vendor it was built by or the environment it's intended to
be used in.
For instance, in Debian I'd use this by configuring with:
--enable-vendor-info="${DEB_VENDOR} ${DEB_VERSION}"
to get a SDL_REVISION like:
release-2.24.1-0-ga1d1946dc (Debian 2.24.1+dfsg-2)
which gives a Debian user enough information to track down the patches
and build-time configuration that were used for package revision 2.
In Autotools and CMake, this is a configure-time option like any other,
and will go into both SDL_REVISION (via SDL_revision.h) and
SDL_GetRevision().
In other build systems (MSVC, Xcode, etc.), defining the
SDL_VENDOR_INFO macro will get it into the output of SDL_GetRevision(),
although not SDL_REVISION.

Clang 15 makes implicit function declarations fatal by default which
leads to some configure tests silently failing/returning
the wrong result.

find_lib() uses sort -V, which is a GNU extension. Users of non-GNU
operating systems should either install GNU coreutils (assumed to
provide a gsort executable), or use the CMake build system.

This reverts commit 8553632827.
An issue with choosing the shortest one, is that it will prefer development libraries: libfoo.so is shorter then libfoo.so.0.6.
SDL makes assumption that each dynamically loaded library must have
SONAME matching pattern <libname>.so.<digit>+ hence it discards any file
that has two (or more) digits after ".so". in practice however SONAME
might be in the form of ie <libname>.so.<major>.<minor>.
as a solution keep requirement for dynamically loaded files to be named
<libname>.so.* but consider all the possibilities and prefer the shortest
one.
