when there are scripts in packages which requires a certain kind of
interpreter e.g. perl. python. bash, sh etc. system can autodetect
that if interpreter is specified in first line of script and add the
appropriate runtime dependency, since this script otherwise will be
useless on target.

I suspect build for dhcp is adding such a file into dhcp-client
package which might be resulting in this implicit dep.

So please check it in the build area for dhcp especially under
packages-split/dhcp-client

for any such scripts.

if there are any and you find that these scripts are not required for normal
functioning of dhcp-client on target then move this script out into
another package where it might be more appropriate, that can eliminate
this rdep
