Eyelink-Linux: Rebuilt with raw sample support enabled on 32 and 64 Bit.

Rebuild mex files for 32-Bit and 64-Bit Matlab/Octave on Linux, now
with raw sample support unconditionally enabled.

Turns out the eyelink_core runtime libraries for 64-Bit Linux provided
on SR-Researchs support website as tar files have been updated with
support early 2012, but the auto-update for Debian Linux systems from
their website still delivers a totally outdated runtime without support!

Really, the correlation between expensive products and incompetent
release and version management never fails to stun me.
