I tried building with cmake for the first time in a long while but it fails
with:

~~~
% cmake ..
[...]
-- Check if the system is big endian
-- Searching 16 bit integer
CMake Error at /usr/share/cmake/Modules/TestBigEndian.cmake:51 (message):
  no suitable type found
Call Stack (most recent call first):
  CMakeLists.txt:816 (test_big_endian)


-- Configuring incomplete, errors occurred!
~~~

CMakeError.log says:

It appears cmake is setting "-fsanitize=undefined" without verifying it
actually works (builds linkable executables).  I'm pretty sure installing the
libubsan package would make the problem go away.
