[Buildroot] [git commit] binutils: fix build of 2.26 when makeinfo is not available

[Thomas Petazzoni]

commit: https://git.buildroot.net/buildroot/commit/?id=de4b45d5e70dd5d2431b0f44aeda60b033ecff11
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

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.
