[SerialICE] SerialICE warnings/errors

[Nils]

Hi All,
I get several warnings and errors and would like to know if they are my fault.

SerialICE_error1:
This warning i get when i first do make menuconfig.
The target is then still qemu.

SerialICE_error2:
This warnings i get always after compiling SerialICE.

SerialICE_error3:
This Segmentation fault i get sometimes when compiling.
After doing again make clean and make it succeeds without segfault.

SerialICE_error4:
This backtrace i get sometimes when compiling.
After doing again make clean and make it succeeds without backtrace.

Thanks, Nils.
