[rescue] Building gcc

I've preferred the stuff from ibiblio (was metalab), their packages seem to 
be more reliable.

I was told it is actually a 3 stage process:

1. Build a compiler from source code with downloaded C compiler.
2. Use compiler generated in step 1 to compile the "real" compiler from 
source code.
3. Use the "real" compiler to compile from source code and compare the 
binaries generated with the "real" compiler binaries.

If steps 2 & 3 produces identical binaries, then you're done.
