Subject: [PATCH] simplify checking for zaptel version and location (for linux,
 this is functionally equivalent to the previous method; for FreeBSD, it
 re-adds inspection in $PREFIX/zaptel.h).

Please wait to regenerate the "configure" file as i have
another few pending changes to configure.ac

Not applicable to 1.4 until acinclude.m4 is also updated.
