Working on fio update on sparc64 and I noticed the libnfs.so <http://libnfs.so/> symbol
_null_auth conflicts with _null_auth in libc.so <http://libc.so/>:

fio:/usr/lib/libc.so.103.0: /usr/local/lib/libnfs.so.3.0 : WARNING: symbol(_null_auth) size mismatch, relink your program

oracle$ objdump -x /usr/lib/libc.so.103.0 | grep _null_auth                                                                                                                                                   
00000000003f61e0 g     O .bss	0000000000000018 _null_auth
oracle$ objdump -x /usr/local/lib/libnfs.so.3.0 | grep _null_auth
0000000000368070 g     O .bss	0000000000000020 _null_auth

I’m not sure what the fix for this should be.
