Re-rerun QEMU + gdb y^M

[nickdesaulniers]

super low priority, but sometimes my prompt gets corrupted when asked to rerun qemu.

I can enter y, but inserts ^M for some reason.

stty icrnl seems to fix this once I quit. Not sure if the below would help, since output from the terminal gets further corrupted it seems...
