Even if gcc 5 is still maintained for some time (gcc 5.5 is pending), switch to gcc 6.x since it has been released since 2016-04-27 and gcc 7.x is available since 2017-05-02. We have been having toolchains in the autobuilders with gcc 6.x for a while, so the vast majority of the problems should have already been solved.

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.
