Why aren't we using -pipe? It can significantly speed up compiles by not
writing temp files (intermediate files).
I don't see harm in adding this?
What do you all think?

Most architectures already uses -pipe - see arch/*/Makefile:
[sam@mars v2.5]$ ls arch/*/Makefile | xargs grep -l -- -pipe | wc -l
17
[sam@mars v2.5]$ ls arch/*/Makefile | wc -l
21

I thought we were. Do you have results to show it speeds up kernel
compiles? I found the opposite when using ext2:

Nevermind, We are using pipe, I just didn't see due to the new Makefile
output (V=1) shows me we are using pipe, at least for ia32.

Unless something has changed recently, -pipe is actually a slowdown.
