scripts/addToolsVersion: properly handle .in vs. .in.2

While most components have their version in the .in file, some
have it in the .in.2 (eg. elf2flt).

Currently, to handle this case, we indiscriminately munge both files,
but this is wrong: in the elf2flt case, if we add a binutils version,
we do not want it to be added to elf2flt, and conversely.

So, for each tool, we need to explicitly know what file to munge.

     1 The m68k mcpu processor does not like unaligned access
     2 
     3 Disable at least mcpu32, m68010 and m68020. These processors certainly
     4 do not like unaligned accesses.
