d0436b2a45 automatically detect configuration changes 
Makefile now automatically detects modifications of compilation flags,
and produce object files in directories dedicated to this compilation flags.
This makes it possible, for example, to compile libzstd with different DEBUGLEVEL.
Object files sharing the same configration will be generated into their dedicated directories.

Also : new compilation variables
- DEBUGLEVEL : select the debug level (assert & traces) inserted during compilation (default == 0 == release)
- HASH : select a hash function to differentiate configuration (default == md5sum)
- BUILD_DIR : skip the hash stage, store object files into manually specified directory

911dbdbb4b build libzstd.so from object files 
%.o object files generated for dynamic library
must be different from those generated for static library.

Due to this difference, %.o were so far only generated for the static library.
The dynamic library was rebuilt from %.c source.

This meant that, for every minor change, the entire dynamic library had to be rebuilt.

This is fixed in this PR :
only the modified %.c source get rebuilt.
