mkbundle-*.sh does not update correctly the $TORBROWSER_VERSION -> $TORBROWSER_BUILDDIR symlink at the end of the build
At the end of a build, mkbundle-*.sh should update a symlink $TORBROWSER_VERSION -> $TORBROWSER_BUILDDIR.
If the symlink already exists it does not update it correctly. This is because the ln command is missing a -T option.
I'm attaching a patch to fix that.
