Thank you for your patch!

Unfortunately, program fails to link properly with --as-needed switch.

$ ld -O1  -shared -o file_hook.so -ldl -lc file_hook.o
$ ldd file_hook.so 
        linux-vdso.so.1 =>  (0x00007fff747ff000)
        libdl.so.2 => /lib64/libdl.so.2 (0x00007f2ceb1ff000)
        libc.so.6 => /lib64/libc.so.6 (0x00007f2ceae73000)
        /lib64/ld-linux-x86-64.so.2 (0x00007f2ceb63e000)
$ ld -O1 --as-needed -shared -o file_hook.so -ldl -lc file_hook.o
$ ldd file_hook.so 
        statically linked

This causes:
symbol lookup error: /usr/lib/file_hook.so: undefined symbol: dlsym

when library is loaded using LD_PRELOAD

I am trying to solve this situation.
