Doesn't seem to make any difference:

[...]
gcc -pthread -shared -Wl,-O1 -Wl,-Bsymbolic-functions build/temp.linux-x86_64-2.6/src/llfuse.o -o build/lib.linux-x86_64-2.6/llfuse.so -Wl,--as-needed -pthread -lfuse -lrt -ldl
copying build/lib.linux-x86_64-2.6/llfuse.so -> src

$ ldd src/llfuse.so 
	linux-vdso.so.1 =>  (0x00007fff63dff000)
	libfuse.so.2 => /usr/lib/libfuse.so.2 (0x00007fe771490000)
	libpthread.so.0 => /lib/libpthread.so.0 (0x00007fe771274000)
	libc.so.6 => /lib/libc.so.6 (0x00007fe770ef0000)
	librt.so.1 => /lib/librt.so.1 (0x00007fe770ce8000)
	libdl.so.2 => /lib/libdl.so.2 (0x00007fe770ae4000)
	/lib64/ld-linux-x86-64.so.2 (0x00007fe77193b000)


Best,
