[Buildroot] [PATCH] eigen: (optionally) install unsupported modules

[Davide Viti <zinosat@tiscali.it>]

Hi Samuel and Thomas,
I can provide a patch that installs the files under
/usr/include/eigen3 and modify my latest patch to install unsupported
under that directory too.

I guess separate patches are preferred.

I can do it later on today.

Regards,
Davide
