This needs another fixup for the Windows build (64bit Mingw64):

C:/msys64/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/10.2.0/../../../../x86_64-w64-mingw32/bin/ld.exe:
 image.o: in function `svg_load_image':
C:/emacs/git/emacs/master/src/image.c:9916: undefined reference to 
`rsvg_handle_get_dimensions'

It looks like the ifdefs for Windows in image.c do not do the runtime import of
rsvg_handle_get_dimensions if librvsg version < 2.46.0, but now it is
needed always.
