speakupmap.h was not actually intended to be source code, speakupmap.map
is.
This resurrects the makemapdata.c and genmap.c tools to generate
speakupmap.h automatically from the input and speakup headers, and the
speakupmap.map keyboard mapping source file.

Any reason you can't add the code in utils.c into genmap.c and then
merge into makemapdata.c to make this a single .c file that does both
things?
And when this is applied, I get the following "extra" files in the tree
that need to be properly ignored, so I couldn't take this as-is anyway:
❯ git status
On branch work-testing
Untracked files:
(use "git add <file>..." to include in what will be committed)
drivers/accessibility/speakup/genmap
drivers/accessibility/speakup/makemapdata
drivers/accessibility/speakup/mapdata.h
drivers/accessibility/speakup/speakupmap.h
nothing added to commit but untracked files present (use "git add" to track)

Yes: genmap is a tool that end-users can use without needing the Linux
source code, while makemapdata needs it.

Oh, right, I'll fix them.

But who will run genmap?
Also you could just put the 90 lines of code into the .h file as inline
functions to get rid of the utils.c to make it a bit simpler.

I guess you meant makemapdata?
Long-term-wise this patchset will need a bit of work to properly install
the genmap tool so the user can call it. I'm here mostly making sure
to put into the Linux kernel how speakupmap.h is generated (rather
than the currently very magic file), while at the same time keeping
the separation between makemapdata and genmap that will make sense
longterm-wise.

Ok, then it's ok to leave it as is. But the build stuff still needs to
get resolved :)
speakupmap.h was not actually intended to be source code, speakupmap.map
is.
This resurrects the makemapdata.c and genmap.c tools to generate
speakupmap.h automatically from the input and speakup headers, and the
speakupmap.map keyboard mapping source file.

difference with v2:
- Stuff utils.c into utils.h
- Add .gitignore
difference with v1:
- Add missing dependency between main.c and speakupmap.h
