AOSP commit a61e4d271cba "Enable adb with android-pipe
in IA image" made GOLDFISH_BUS modular (i.e switched it
to "tristate" in Kconfig from "bool"), which is not
buildable. Instead of fixing the build and supporting
it in modular form, which AOSP doesn't agree with anyway,
lets restore it to the original state ("bool") in the Kconfig.

A QEMU pipe is a very fast communication channel between the
guest system and the emulator. Usage from the guest is simply
something like;
// connect to special device
fd = open("/dev/qemu_pipe", O_RDWR);
// tell which service we want to talk to (must be zero-terminated)
write(fd, "pipeName", strlen("pipeName")+1);
// do read()/write() through fd now
...
// close channel
close(fd);
