Vladislav Vaintroub 3cb24fff33 - Always compile my_new.cc and safemalloc.c with mysys
Preprocessor macros USE_MYSYS_NEW and -DSAFEMALLOC are 
used to conditionally compile safemalloc or overwritten new/delete.

-Define dummy symbol in my_new.cc in case -DUSE_MYSYS_NEW is not set.
This avoids compiler/linker warnings about an essentially empty file
being compiled.
