Fixing "error: taking address of packed member of ‘struct QCowHeader’ may result in an unaligned pointer value"

gistfile1.txt

Qemu issue:
```
error: taking address of packed member of ‘struct QCowHeader’ may result in an unaligned pointer value
```

Went into `configure` and removed all `-Werror`

Also had to edit `/home/daniel/Pulled/qemu-eos/qemu-2.5.0/hw/arm/../eos/dbi/backtrace.c:768` and  
replace `scnprintf` with `sprintf`.  

Also make sure you install everything:
```
sudo apt install mercurial build-essential gcc-arm-none-eabi gcc-multilib libc6-dev:i386 python-docutils
```
`module_strings.h` may not be included if you don't
