It's just a git tree for Linux in which I've checked-out the
v6.0-rc1 tag and applied few unrelated patches on top.

The thing confused me a bit as all other artifacts were properly
placed in the output dir with an exception of the speakupmap.h.

My guess would be that I had some cache left over in the build dir
from before this patch, when the file was hardcoded so it tried to
recreate it as it was. This seems reproducible:

(Please note that the build tooling I use handles the output dir in
the output below)

$ sudo rm -rf .output/drivers/accessibility/speakup/
$ git checkout v5.19
$ make -j12 allnoconfig
$ make -j12 menuconfig # Enable speakup
$ make -j12
(... Builds correctly)

$ git checkout v6.0-rc1
$ git cherry-pick bc239d8740f9
