It's looking like the package built for the native system.  Either
that or you're trying to mix and match the target libraries in the
same directory (bad idea).  The .so files are not for the windows
target.  Maybe you misconfigured the library package - when cross
compiling you probably need to specify
--host=x86_64-w64-mingw32

not

--target=x86_64-w64-mingw32

The --target parameter is used only when creating a cross compiler
(telling the compiler what it's going to be targeting).   While
normally you'll specify --host, which tells the configuration routines
what the machine you will be RUNNING the result on.
