    lua: add -ldl for glibc builds
    
    For glibc, lua needs an explicit link to libdl as glibc has it separate
    
    Fixes the following error in at least collectd:
    
    ld: usr/lib/liblua.so: undefined reference to `dlopen'
    ld: usr/lib/liblua.so: undefined reference to `dlclose'
    ld: usr/lib/liblua.so: undefined reference to `dlerror'
    ld: usr/lib/liblua.so: undefined reference to `dlsym'
