machine exceptions to POSIX signals. This is required for some languages
such as Ada.

/**
* @brief This configuration option is a boolean feature define.
*
* In case this configuration option is defined, then the machine exception to
* POSIX signal mapping is configured during system initialization.
*
* @par Default Configuration
* If this configuration option is undefined, then the described feature is not
* enabled.
*
* @par Notes
* @parblock
* This device driver is responsible for setting up a mapping from machine
* exceptions to POSIX signals so that applications may consume them and alter
* task execution as necessary.
*
* This is especially useful for applications written in Ada or C++.
