    BSE: check for writable /etc/ld.so.cache before running /sbin/ldconfig
    
    Only root or sudo environments can execute /sbin/ldconfig. Detecting
    this via `id -u`==0 breaks fakeroot, which cannot write /etc/ld.so.cache.
    Actually checking for a writable /etc/ld.so.cache covers all cases.
