* Ability to run linux tests with AddressSanitizer
This makes it possible to compile and run the tests with Address
Sanitizer (ASAN) [1].
The command is:
```
make -f custom.mk clean; ASAN=1 make -f custom.mk && ./build/win_main -runUnitTests 2
```
Building without ASAN works without change.
Address Sanitizer saves a lot of time debugging memory issues, for
example for a bug where we index in an array with negative index it
gives this nice error message:
```

* disable tests broken on linux
* add a suppression file for known leaks
* attempt at adding an ASAN workflow
* fix autogen
* Update workflow.yaml
