    devel/libgudev: fix build with clang 18

    Clang 18 no longer accepts -export-dynamic, which is a linker option,
    resulting in an error building devel/libgudev:

      cc  -o gudev/libgudev-1.0.so.0.3.0
gudev/libgudev-1.0.so.0.3.0.p/meson-generated_.._gudevenumtypes.c.o

/usr/local/lib/libgobject-2.0.so /usr/local/lib/libudev.so -Wl,--end-group
      cc: error: unknown argument: '-export-dynamic'

    Fix this by using the correct spelling, -Wl,--export-dynamic.
