AM_DISTCHECK_CONFIGURE_FLAGS

[Sergey Poznyakoff]

Hello,

Sometimes it is necessary to always use certain configure
options during distcheck. For example, in GNU cpio we do
not build `mt' by default, but we'd like to always build
it during distcheck, to ensure that nothing went wrong with
it. That could be achieved if automake used
AM_DISTCHECK_CONFIGURE_FLAGS variable, along with
DISTCHECK_CONFIGURE_FLAGS. How about the attached patch?

Regards,
Sergey
