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.

ARMV5 can use STRD and LDRD access instructions but these accesses need to be
