To build for release

 cd release
 make
 make check

  You get two libraries in release/lib
    libsupermalloc.so             requires transactional memory (haswell)
    libsupermalloc_pthread.so     uses pthread locks
  I plan to add a runtime check and have only one library and an enviroment variable in the future.

------

You should also build and check with the internal testing code
enabled.  It's a different library partly because of link-time
optimization.  Also, if you want things easier to compile.  There are
two differences, we enable the TESTING flag (which includes a bunch of
code that can be compiled) and we set -O0.

 cd debug
 make check

-------
To run code coverage 
 cd coverage
 make check

-------
At top level you can do
 make clean
 make
 make check
