cmake: Only pass -Wl,--export-dynamic when linking

Browse source 
Otherwise we get the following warnings when building .o files with Clang:
clang-13: warning: -Wl,--export-dynamic: 'linker' input unused [-Wunused-command-line-argument]

This is required to allow the -Werror build to pass on FreeBSD.
