The exim install script installs a binary named exim-<version>, plus a symlink
to it named exim.
In order to achieve this "feature" (of dubious usefulness) it runs the
executable (on the host) and then filters its output to grab the version number.
This clearly cannot work if the executable is cross-compiled, so get rid of all
of it and just install an executable file called exim.
