binutils/binutils: fixup version strings

Recently, all binutils versions have been renamed after a GPL compliance
issue was found and fixed in binutils;
http://sourceware.org/ml/binutils/2011-08/msg00198.html

Old versions are no-longer available since the rename (eg. 2.19 has been
superseeded by 2.19.1, and only 2.19.1a was regenerated).

Remove now-missing versions.
