Subject: [PATCH] autotools: relax soname pattern for dynamic loading

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.

Fixes: #289
From: libsdl-org/SDL#5901
