Comment:
I can't make it not rebuild `fixdep` using the new `HOSTCC`. One plan was to build it for host first, build the others programs and finally rebuild it for the target.

See `make -d` output:

I have no idea how to bypass this `FORCE` thing.

I have no idea how to bypass this `FORCE` thing. `FORCE` is a `PHONY`, so it isn't even possible to temporarily create a file named FORCE.

https://github.com/void-linux/void-packages/pull/29952#issuecomment-816331699

Comment:
Debian has a set of Makefile to build those tools.
My bigger concern is the tools usage:
- Is it for using natively on cross-target?
- Is it usable for cross-compiling an OOT module (let's say with -mklive)?

Will be fixed for 5.12 using leah's patch for 5.10. Should be imported into rpi-kernels once those are updated.

Description:
Since we are here, clean up unused args and add a few comments.

<!-- Mark items with [x] where applicable -->

#### General
- [ ] This is a new package and it conforms to the [quality requirements](https://github.com/void-linux/void-packages/blob/master/Manual.md#quality-requirements)

#### Have the results of the proposed changes been tested?
- [ ] I use the packages affected by the proposed changes on a regular basis and confirm this PR works for me
- [ ] I generally don't use the affected packages but briefly tested this PR

<!--
If GitHub CI cannot be used to validate the build result (for example, if the
build is likely to take several hours), make sure to
[skip CI](https://github.com/void-linux/void-packages/blob/master/CONTRIBUTING.md#continuous-integration).
When skipping CI, uncomment and fill out the following section.
Note: for builds that are likely to complete in less than 2 hours, it is not
acceptable to skip CI.
-->
<!-- 
#### Does it build and run successfully? 
(Please choose at least one native build and, if supported, at least one cross build. More are better.)
