how I can configure openjdk/Icedtea with HEADLESS enable

[Diaz Soho]

Hi all,

I would like to use openjdk/Icedtea with JamVM  for my embedded
platform. My embedded platform does not include graphic function. I
would like to build a HEADLESS version. I can set the
option(--disable-headful) while configuring jdk8u. But I can not the
option (--disable-headful) when I try to configuring IcedTea.

how to disable X11 related in Icedtea?
Any ideas?

Best Regards,
