*morning english is broken english*
I'll rephrase this:
As the commit line say, it removes unused linker scripts. This commit
intended to be really dumb: unused = delete. And since I wasn't sure
mbr/x86_64/mbr.ld was actually used, I left it. I'll remove it and
move mbr/i386/mbr.ld to mbr/mbr.ld in a second version of this patch
series.

Anyway, I think it's better to separate the dumb commit that remove
the unused scripts from the more "risky" ones that may actually have
an effect. Should it be to simplify bisection.

If I may, I'd make a parallel with whitespaces commits. There are two
ways of thinking:
- either you only fix the whitespaces around the lines you actually change ;
- or you fix the whitespaces of a whole file and make the changes a
separate commit.

Since I had several other files to delete, I choosed the latter way.
