This closes a bug on older 32-bit platforms, where the 16-bit setgroups
syscall has been replaced by setgroups32 and is not available anymore.
Signed-off-by: Markus Schaaf <markuschaaf@xxxxxxxxx>
(Personal note: Reporting a trivial bug and getting a fix upstream in
nfs-utils is like running the gauntlet, for the uninitiated average user.)
