commit 8f4c39af7bb562e6d65e4ecf11d2311575637284
Author: Marco Casaroli <marco.casar...@gmail.com>

    libs/libc/unistd: Return ARG_MAX from sysconf(_SC_ARG_MAX).
    
    unistd.h defines _SC_ARG_MAX and limits.h defines ARG_MAX, but
    sysconf(_SC_ARG_MAX) returned -1 with ENOSYS.  POSIX lists
    _SC_ARG_MAX as a name that sysconf() must support.
    
    Return ARG_MAX.
