Hi Rusty,

I have a couple of nfsim fixes for x86_64. Please review and apply the 
correct ones.

Thanks,
Patrick


This patch fixes a linker error on x86_64 when linking core/fakesockopt.o:

gcc -Wmissing-prototypes -Wstrict-prototypes -Wunused -Wall -g -Wa,-W 
-shared -Wl,-soname,fakesockopt.so.1 -nostdlib -ldl \
        -o core/fakesockopt.so.1.0 core/fakesockopt.o core/utils.o
/usr/bin/ld: core/fakesockopt.o: relocation R_X86_64_32S can not be used 
when making a shared object; recompile with -fPIC
core/fakesockopt.o: could not read symbols: Bad value
collect2: ld returned 1 exit status
make: *** [core/fakesockopt.so.1.0] Error 1
