1. Link crt*.o to correct place :
root@neou11:/usr/lib# ls /usr/lib/crt* -l
lrwxrwxrwx 1 root root 32 2012-03-04 02:37 /usr/lib/crt1.o -> /usr/lib/x86_64-linux-gnu/crt1.o
lrwxrwxrwx 1 root root 32 2012-03-04 02:37 /usr/lib/crti.o -> /usr/lib/x86_64-linux-gnu/crti.o
lrwxrwxrwx 1 root root 32 2012-03-04 02:37 /usr/lib/crtn.o -> /usr/lib/x86_64-linux-gnu/crtn.o
2. Use GCC 4.6 instead of 4.4 :
neo@neou11:~/work/edk2-12898/UnixPkg$ svn diff build64.sh
