Hello,
The current --disable-headful option is weird. Even worse, it doesn't
work since the makefiles still uses the legacy BUILD_HEADLESS_ONLY
variable, which configure never touches.
In this patch I'm replacing the configure option with
--enable-headless-only. Default is disabled, where both headless and GUI
support is built. When enabled, only headless support is built. These
are the two variants we are ever interested in.
On the makefile side, I redefined the variable as
ENABLE_HEADLESS_ONLY=true/false.
I also needed to change jawt.c to get a headless only build to actually
work. The requirement that -DJAVASE_EMBEDDED is set seems unnecessary
and unrelated to me.
