  Some via cpus in the past didn't have an instruction gcc  used for 
i686.  But if you can bootstrap the first compiler and build glibc, I 
doubt that is the problem.

  Segmentation faults ('signal 11') are usually a sign that something is 
not well - bad memory, insufficient processor cooling, perhaps bad power 
supply.  But, gcc and glibc are usually a much harder test of the 
machine, and failing in the exact same place is not especially common.

  I recommend running memtest86+ for several hours.  Via epias tend to 
come in exotic cases, you might want to check if the cooling seems 
adequate (e.g. use any bios readings, or feel how hot any external 
metalwork gets).
