What steps will reproduce the bug?

Configure node to use the cross-compile rules with ninja, then try building it:

$ ./configure --cross-compiling --ninja && make
Node.js configure: Found Python 3.10.6...
INFO: configure completed successfully
ninja -C out/Release
ninja: Entering directory `out/Release'
ninja: error: obj.host/tools/v8_gypfiles/run_torque.ninja:1451: multiple rules generate gen/torque-generated/bit-fields.h [-w dupbuild=err]

This doesn't happen if using ninja but not cross-compiling, or if cross-compiling without ninja.

How often does it reproduce? Is there a required condition?

The exact same behavior also occurs on v16.x branch.

I don't think cross-compiling with ninja has ever worked. For anyone wanting to work on this, it probably requires applying fixes to https://github.com/nodejs/gyp-next/blob/main/pylib/gyp/generator/ninja.py

Seems like a duplicate of #37441.

Also if you scroll down you can see that a fix (or workaround) is available in a fork minrk@5e533cb, which is in use by buildroot

Oh, indeed it is. I'll close it as such then.
