The mentioned 'liboSettings.gradle' should actually be generated during 
the top-level make, so that sounds like that one isn't doing what it 
should in your case.

This is using NDK 25.2.9519653. From what commit are your trying to 
build? Does the top-level make succeed for you?

In my experience, building with NDK 25 required changes, s. 
https://gerrit.libreoffice.org/c/core/+/146135 (and change further down 
in the relation chain).

If you haven't applied these changes yet, I'd suggest to either do that 
or build with an older NDK until these changes have been merged to 
master (currently waiting for the new NDK to become availabe on Jenkins 
builders).

FYI, my autogen.input on Debian testing for master as of commit 
b2bd60b8c1937502857e12b0eea42323fd2353c8 currently looks like this:
