Fix strict-aliasing warning in dlmalloc
This fixes the following warnings in dlmalloc seen with my gcc 4.6. dlmalloc.c: In function 'malloc_bin_reloc': dlmalloc.c:1493: warning: dereferencing pointer 'p' does break strict-aliasing rules dlmalloc.c:1493: warning: dereferencing pointer 'p' does break strict-aliasing rules dlmalloc.c:1490: note: initialized from here dlmalloc.c:1493: note: initialized from here This version is tested on avr32 arch boards.
