Eyelink for 32-Bit Linux: Enable raw data access functions.

The raw data access subfunctions are supported by latest Eyelink
runtime libraries (v1.9 from 25th March 2011) for 32-Bit runtimes ie.,
32-Bit Matlab and 32-Bit Octave.

The same functions are *not* supported for the same library version on
64-Bit setups!
-> Rebuild 32-Bit Octave/Matlab mex files for Linux with support
enabled.
