When SDL is built with Wayland support on Linux, and Wayland libraries are linked as dependencies instead of being loaded with dlopen(), its dependencies will include libraries whose names contain a dash, like `-lwayland-client` and `-ldecor-0`. Don't replace such libraries with `-lwayland` and `-ldecor`: those don't exist and linking them will fail. Signed-off-by: Simon McVittie <smcv@collabora.com>
