The following script was applied:
sed ':a;/part of MXE.$/{N;s/\n//;ba}' -i $(git grep -l 'part of MXE')
sed 's/\(part of MXE\).*\(See index.html\)/\1. \2/' -i \
$(git grep -l 'part of MXE.*See index.html')
before='This file is part of MXE. See index.html for further information.'
after='This file is part of MXE. See LICENSE.md for licensing information.'
sed "s/$before/$after/" -i $(git grep -l 'part of MXE')
Then git grep 'index.html for further information' revealed two other files.
One of them was patched manually (patch.mk). Makefile has text
"See index.html for further information" unrelated to licensing.

Many FTP servers block connections from Tor and some
VPN servers. HTTP servers don't do this normally.
Example of failed FTP download attempt of binutils-2.24.tar.bz:

Trying download from Tor Browser, I get error message:
425 Security: Bad IP connecting.
HTTP URLs were added to FTP URLs-only packages.
In many cases, ftp://ftp.gnu.org can be accessed
from http://ftp.gnu.org
If both URLs of a package are FTP, then one of them
was replaced with HTTP.
Command to check that those packages can be build successfully
if behind Tor:
$ torsocks make autoconf automake binutils bison cloog coreutils file freetds gcc gdb gettext gmp gnutls gperf isl libbluray libffi libgcrypt libgpg_error libidn libmicrohttpd libpng libxml2 libxslt m4 pthreads-w32 sed dcmtk mpfr
I've run the test above successfully.
