libmudflap is a gcc library used for the mudflap pointer

debugging functionality. It is only needed if you intend to

|
use the -fmudflap gcc flag.
|
|
|
|
See http://gcc.gnu.org/wiki/Mudflap_Pointer_Debugging and
|
|
the help of the gcc -fmudflap option for more details.

If you're unsure, leave this option disabled.
