musl libc doesn't support the GNU getopt extension to parse non-option arguments when the optstring starts with '-'. This extension is used by some utilities, notably iptables, that currently return with errors even with perfectly valid invocations. The patch adds the code needed by getopt.c and getopt_long.c to implement that extension. Signed-off-by: Gianluca Anzolin <gianluca@sottospazio.it> SVN-Revision: 43309
