Remove usages of GCC __attribute__.
...
- To allow clang to compile, as it doesn't according to #58 .
- The target attributes are not needed anymore due to makefile handling
targetting now.
- The __attribute__((unused)) used for debugging. I don't know if clang
supports this attribute or not but it doesn't seem very important so
I'm removing it just in case.

strategies/avx2/dct-avx2.c:334:25: error: pasting "g_dct_16" and "[" does
not give a valid preprocessing token
- The [ is not part of the token so compilation failed on mingw GCC 4.9.1.
- Fixes #86 .
