I am using quilt to manage patches internally. Quilt creates dir .pc
and stores unmodified files there. Since I made change in one of
Config.src quilt made a copy in .pc/xxx.patch/xxx/Config.src. When
I run make it calls gen_build_files.sh and it generates
.pc/xxx.patch/xxx/Config.in. Now when I want to pop patch quilt
thinks I have made changes to original xxx/Config.in.
IMO the best solution is just to ignore hidden directories in
gen_build_files.sh. This also results in shorter build time in case
busybox is under git/svn versioning, since it avoids searching
many directories for Config.src.

The shell parsing of files is incredibly slow on many systems. With
one report, the process was taking a minute or two which made people
thing the build was hung. So rewrite the craziness with sed and proper
shell functions. On an idle system, this cut the runtime by half.

While doing O=build build I've noticed that it was getting gradually
slower with each invocation. The reason turned out to be that the build
directory was inside the source tree and got recreated inside itself
with all its subdirectories.
This patch changes the behavior so that only the directories with
Kbuild.src or Config.src in them are created in the out-of-tree build
directory. A quick rebuild from scratch revealed no problems with this.
