I was trying to do a fresh build of master with the address sanitizer
enabled in Clang, and I am receiving a strange linker error, and was
curious if anyone else had any thoughts on it.

When it tries to link the eeschema executable, it throws an error
complaining about a missing Kiface symbol:

That symbol is defined in the _eeschema.kiface module though.

The verbose linker message is attached. Does anyone have any thoughts as to
why it seems the executable is unable to find the symbol when I enable the
address sanitizer?

Thanks,
