MATLAB breaks minc-toolkit-v2 built with shared libraries when used under system('') calls

[gdevenyi]

MATLAB's launcher defines a bunch of LD_LIBRARY_PATH, which includes their HDF5 library. They don't mangle symbols like ITK does, so there's a library conflict, and the minc tools all bail out.

The reason for this is we're using RUNPATH during linking, which is lower presidence than RPATH.

I've reported this to MATLAB as a bug (they should use RUNPATH/RPATH for their builds, or mangle their symbols).

A static build fixes this.
