java-package does not work, fix included

[Marcus Sundman]

$DEB_BUILD_GNU_TYPE is not necessarily "i386-linux", so make-jpkg doesn't 
work. The following patch should fix it when applied to
BOTH sun-j2sdk.sh AND sun-j2re.sh:
-------8<----------------------------------------------------------
5,6c5,7
<   case "$DEB_BUILD_GNU_TYPE" in
<     "i386-linux")
---
>   _DEB_BUILD_GNU_TYPE="${DEB_BUILD_GNU_TYPE%%-gnu}"
>   case "$_DEB_BUILD_GNU_TYPE" in
>     "i"[3-6]"86-linux")
------->8----------------------------------------------------------
