7537406edd build system: specify '-nostldlib' when linking to .o files
For certain cross build scenarios the LD variable is overridden
to use the gcc executive to ensure all the target tuning parameters
are used.  In these cases, the executive errors out as shown below
but since this step is only linking to a .o file the standard libs
are not needed.

    $ make LD=gcc applets/built-in.o

3eab2b7675 trylink: only prefix libs with -l
If our pkg-config queries pass back a flag like -pthread, the trylink
script will expand that to -l-pthread.  So change trylink to only add
the -l prefix to a value that doesn't have a - prefix already.

9078633fee buildsys: Add helper to list suid applets
Add a helper script that lists all applets that
- do or may require SUID provileges (busybox.cfg.suid)
- do not require SUID provileges (busybox.cfg.nosuid)

Some setups prefer to build two busybox binaries, one that is suid which
contains all applets that do or may require suid privileges, and a
second one for all the rest (which drops suid). To ease splitting these
two binaries, generate a list of CONFIG_ items for the suid binary.

1c7724bf2a gen_build_files.sh: exclude hidden directories
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.

f718e3a0db gen_build_files.sh: rewrite with sed
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.
