build(autotools): fix MSYS2 build (#2818)
A bit of history on this fix:
MSYS team removed removed shared libdl.dll and libdl.dll.a
commit:
https://github.com/msys2/MINGW-packages/commit/c27ad107f7df624604c96f45d124b761b6fc0aa9
discussion: https://github.com/msys2/MINGW-packages/issues/7548
When compiling synfig it shows the warning:
```
*** Warning: linker path does not have real file for library -ldl.
*** I have the capability to make that library automatically link in when
*** you link to this library. But I can only do this if you have a
*** shared version of the library, which you do not appear to have
*** because I did check the linker path looking for a file starting
*** with libdl and none of the candidates passed a file format test
*** using a file magic. Last file checked: C:/msys64/mingw64/lib/libdl.a
```
This happens because
(cite from here:
https://github.com/msys2/MINGW-packages/issues/7548#issuecomment-753619221):

This leads to the impossibility of linking with libdl.dll and for this reason
the
loading of modules do not work. This is why images can't be built.
AppVeyour CI build works because it uses CMake toolchain.
P.S. Debug build still doesn't work due to another issue.
