binutils: fix build of 2.26 when makeinfo is not available
The 2.26 binutils tarball has incorrect timestamps for the .info files,
so binutils build system tries to regenerate them with makeinfo. In
order to avoid depending on host-texinfo, we simply touch the .info
files so that their timestamp is newer than the corresponding source
files.
