findutils: Fix compilation for x32 toolchain

Work around gnulib time_t assumption in findutils for x32

time_t is 64bit and long int is 32bit on x32.  But gnulib used in
findutils assumes time_t values fit into long int.  Such assumption is
invalid for x32 and should be removed.

This patch is a workaround to compile gnulib for x32.
