Alejandro González 95b0078cc0 package/iputils: add config options to select which binaries to build/install
By default, the iputils build script might build binaries which are
useless for certain applications, like tftpd or ninfod. Those binaries
will add to the target filesystem size unless a post-build script removes
them manually, which is cumbersome and doesn't shorten build times.

In particular, in a certain aarch64 Buildroot project with musl selected
as a C library, this patch allowed to shrink the full iputils package from
219 KiB (if every option is selected) to 63 KiB (with only the ping
binary selected) - a 71.2% relative size decrease.

Moreover, upstream recently introduced a commit that disabled tftpd from
building by default, like rarpd. In the current state of things, this change
will introduce inconveniences for Buildroot users which prefer to use the
tftpd implementation provided by this package. With this patch, however, that
decision and similar future ones won't be a concern, because they will
have complete control of what binaries are built.

These changes add Kconfig options which let the user select what
binaries are built with ease.

README

Buildroot is a simple, efficient and easy-to-use tool to generate embedded
Linux systems through cross-compilation.

The documentation can be found in docs/manual. You can generate a text
document with 'make manual-text' and read output/docs/manual/manual.text.
Online documentation can be found at http://buildroot.org/docs.html

To build and use the buildroot stuff, do the following:

1) run 'make menuconfig'
2) select the target architecture and the packages you wish to compile
3) run 'make'
4) wait while it compiles
5) find the kernel, bootloader, root filesystem, etc. in output/images

You do not need to be root to build or run buildroot.  Have fun!

Buildroot comes with a basic configuration for a number of boards. Run
'make list-defconfigs' to view the list of provided configurations.

Please feed suggestions, bug reports, insults, and bribes back to the
buildroot mailing list: buildroot@buildroot.org
You can also find us on #buildroot on Freenode IRC.
