crosstool-ng: patches/gcc/3.4.6/160-arm-ldm-peephole2.patch@c72aecd1a9ef

Get rid of all stuff related to building a /delivery' traball:
- building a delivery tarball has long been broken (since crostool-Ng is installable)
- get rid of implied do_print_filename, that can be mis-leading now tarballs can not be built
