Since 3.8 (included), the following build command fails:

    LDFLAGS=-headerpad_max_install_names ./configure

With the following error: error: argument -h/--help: ignored explicit argument 'eaderpad_max_install_names'

A quick hack in "fixes" the issue:

-                options, _ = parser.parse_known_args(env_val.split())
+                options, _ = parser.parse_known_args([x for x in env_val.split() if not x.startswith('-h')])

Another workaround as a user is to do use `LDFLAGS=-Wl,-headerpad_max_install_names`.

@ux, could you please provide more information? What platform are you on, and what compiler version produces this error?

Inada: adding you as you merged the patch that made the switch optparse->argparse.

Thanks for the report, @ux, and thanks for the PR, Andrei! I've backported the fix for release in 3.10.1 but I think it's pretty late in 3.9's release cycle and we've lived this long with the issue.

I agree re: 3.9, thanks Ned!
