Bug 521515: [releng] Build o.e.cdt.native.serial natives using docker

Steps:
1. Edit and commit change
2. docker run --rm -it -v $(git rev-parse --show-toplevel):/work -w /work/$(git rev-parse --show-prefix) quay.io/eclipse-cdt/cdt-infra-eclipse-full:latest  make -C jni rebuild
3. GIT_COMMITTER_DATE=$(git log -1 --pretty=format:%cI -- .) git commit --amend -a --reuse-message=HEAD

+### How to rebuild natives.
+
+The goal of these instructions is to have a cross-platform build of the natives in CDT. Using tools in CDT's 
+[docker](https://github.com/eclipse-cdt/cdt-infra/blob/master/docker/cdt-infra-eclipse-full/ubuntu-18.04/Dockerfile) build image
+(quay.io/eclipse-cdt/cdt-infra-eclipse-full:latest).
+
+It is fairly straightforward to biuild the natives, run this command:
+
+```
+docker run --rm -it -v $(git rev-parse --show-toplevel):/work -w /work/$(git rev-parse --show-prefix) quay.io/eclipse-cdt/cdt-infra-eclipse-full:latest  make -C jni rebuild
+```
+
+However, the challenge is that dll files on Windows have a timestamp in them. To have reproducible builds, we need to have a reproducible 
+timestamp. Therefore we use the commit time of the commit to derive a timestamp (See the Makefile for more info). Because we want
+to keep the DLL checked in so that contributors don't need to rebuild it all the time we need a way to have to check in the dll with 
+the same commit time. To do this we use GIT_COMMITTER_DATE. So, after editing and committing your change, you need to rebuild one last
+time with the commit date and the commit it without changing the commit date again using:
+
+```
+GIT_COMMITTER_DATE=$(git log -1 --pretty=format:%cI -- .) git commit --amend -a --reuse-message=HEAD
+```
