 We already have one: BR2_PACKAGE_GDB_HOST.

 Other possible candidates are the installers for boot loaders (grub, 
syslinux), target image manipulation programs (parted, fdisk, e2fsprogs, 
uboot-tools), tools to communicate with the target (openocd, tftpd), and maybe 
even scripting languages for running test suites (expect, python).

 However, I'm not sure of the value of having these in the .config.  If I need 
them, it's anyway for use in build scripts that run on top of buildroot, and 
then I can just run a "make world host-e2fsprogs".  The paths to the host 
tools are anyway so long that even when you need them in your shell, typing an 
additional make host-xxx first is really no effort.

 That would mean they don't sit in their package's Config.in.  Still, it would 
be the most logical place.  Anyway there normally is no impact on the 
package's makefile since the config option is taken care of by GENTARGETS.

 I don't have anything against it.  But no real driving reason for it either.

 Similar as for the boundary between when to have a configuration option for 
different versions of a package.  Depends on what users need.


 Can someone summarize the arguments that were used when this discussion took 
place a few years ago?
