A testdir of module 'argp' fails to compile on Haiku:
../../gllib/argp-eexst.c:30:32: error: 'EX_USAGE' undeclared here (not in a
function)
error_t argp_err_exit_status = EX_USAGE;
^
Makefile:1633: recipe for target 'argp-eexst.o' failed
make[4]: *** [argp-eexst.o] Error 1
This patch fixes it.

sysexits: Fix for Haiku.
* lib/sysexits.in.h: Don't assume that <sysexits.h>, when it exists,
defines anything.
* doc/glibc-headers/sysexits.texi: Mention the Haiku bug.
