[PATCH 14/21] getdtablesize: do not use getrlimit() on OS/2 kLIBC

[KO Myung-Hun]

getrlimit() was implemented in kLIBC and works well. Strangely,
however, it crashes due to 'stack overflow' or 'SIGSEGV' when used in
GNU M4. So just use getdtablesize().

* lib/getdtablesize.c (rpl_getdtablesize): Do not use getrlimit() on
OS/2 kLIBC.
