platform_build_soong/tests/bp2build_bazel_test.sh
Lukacs T. Berki 56ebaf35b3 Separate the files of bp2build and soong_build.
The following files are forked:

- build-globs.ninja
- The glob list files
- .d files for the glob list files
- The output file (build.ninja or the bp2build marker file)

This makes bp2build and soong_build not overwrite each other's files
they need for proper incrementality.

Test: Presubmits.
