[issue17819] removes need for CONFIG_SITE external configuration

[Antonio Cavallo]

New submission from Antonio Cavallo:

This patch introduces two new options (--enable-ptmx, --enable-ptc) to  
the configure script.

In cross compile the actual code requires an external config.site config file to
set the result values for the AC_CHECK_FILE macros on /dev/ptmx, /dev/ptc.

These flags forces (if given) the result of the AC_CHECK_FILE macros: if the flags aren't given then the AC_CHECK_FILE tests are run as normal providing an error message when in cross compile mode (explicit behavior).
