Comment:

 I don't see the problem, you just do:

 {{{
 test-suite blah
   type: exitcode-stdio-1.0
   main-is: tests.hs
   ghc-options: -O2 -DTESTING
   build-depends: base >= 4.2 && < 5, array, deepseq >= 1.2 && < 1.3
   ... etc
 }}}

 That is, the test suite does not depend on the containers lib, it includes
 the modules directly and so it can specify extra ghc cpp flags.

 Note that you would not want to use `if enabled(tests)` to use `-DTESTING`
 on the main library since that would change the library. Users installing
 the package and for extra paranoia automatically running the testsuite
 would end up with a non-standard, possibly slower package.
