Comment 5 for bug 252652

> You can't download it because PPA doesn't support PPC architecture.
I went to the deb-src URL ([0] and [1]) directly, and use wget to download the source (the .tar.gz and .diff.gz). In the makefile, ppc arch is supported (so does ppc64). Not sure what do you mean by: PPA doesn't support PPC architecture.

> Anyway, in order for PPC arch to be available, you can compile code with -fno-stack-protector, you should have no problems then.
1) what does -fno-stack-protector do? Is it required for ppc and ppc64?
2) If so, we should add this option to the makefile for ppc64 (ppc always has this option).

In any case, I add this option to fgetty (not to dietlibc), and changed CROSS to ppu- in both Makefiles. fgetty works great. Thanks!

FYI, here is memory comparison:
 before login:
            VIRT RES SHR
 getty: 1864 612 544
 fgetty: 120 28 12
 after login:
 getty: getty is gone, but login stays, with about 1200k memory
 fgetty: both fgetty and login are gone.

So basically, for each tty, fgetty saves about half mega memory before login, saves 1M after login. Ubuntu comes with 6 ttys by default. So that is 3M, 6M respectively. This is significant savings for PS3.

We should makes this as the default for PS3, unless someone seems a drawback...
