Native library debug files contain the full gcc system include paths, which then results in the native library being non-reproducible (via the CRC bytes), if built with differing gcc include path location.
This is especially noticeable when using a bespoke DevKit, with the intention of reproducible builds by using it, however the non-standard DevKit path to the includes immediately makes it non-reproducible.

eg. strings dump of libnet.debuginfo:
/home/andrew/jdk21u/build/devkit/result/aarch64-linux-gnu-to-aarch64-linux-gnu/aarch64-linux-gnu/sysroot/usr/include/sys
