libreoffice and x86 (32 bit) Version on x86_64 Systems?

[ChrisJumper]

Dear gentoo community and developer team!

I have some bad plugins for my libreoffice like a spell checker program. Thats only supported by an 32bit-Java-Plugin.

It works if i download and install the x86-binary from libreoffice.org. Would be nice if portage do the update check and installation it for me. Here is my Question: Could i use/create an Overlay with a personal ebuild? In this case i still had to check and update it by hand, or there a method to download and install the x86 Version while emerging libreoffice-bin?

Perfect would be a useflag at the libreoffice-bin package that handle the architecture, or some hind if the package use x86 or native x86_64 binary. Sine some binary packages come with 32bit (firefox-bin) and some with 64bit (libreoffice-bin). Of course i could take a look in the ebuild but a useflag would be more comfortable.

regards and Merry Christmas / happy Holidays!
