2014-06-22find: use sysconf(_SC_ARG_MAX) to determine the command-line size limitDenys Vlasenko
The find utility uses a hardcoded value of 32 * 1024 as the limit of the command-line length when calling 'find -exec ... {} +'. This results in over 4 times more execve() calls than in coreutils' find. This patch uses the limit defined in system headers. Based on the patch by Bartosz Golaszewski <bartekgola@gmail.com>.

It is impossible to formulate sane ABI based on size of ulong because it can be 32-bit or 64-bit. Basically it means that you cannot portably use more that 32 option chars in one call anyway... Make it explicit.
