Model fails to build because "lcc64tools.mak" is missing in R2016b

When I try to build my model, I get the following error message:

Environment variable error not defined
ModelMakeFile.mk:181: \rtw\c\tools\lcc64tools.mak: No such file or directory
gmake: *** No rule to make target '\rtw\c\tools\lcc64tools.mak'. Stop.
### Build procedure for model: 'ModelName' aborted due to an error

How do I resolve this error?

This error is likely the result of a corrupted installation of MATLAB.  The error can be resolved by uninstalling and reinstalling MATLAB.
