Introduces a BAZEL_JAVAC_OPTS environment variable to the bootstrap build with empty default value to keep the script behavior unchanged. javac is not given a large enough max heap on Raspberry Pi 3. This change but allows the user to override the setting.
RELNOTES:
The BAZEL_JAVAC_OPTS environment variable allows arguments, e.g., "-J-Xmx2g", may be passed to the javac compiler during bootstrap build. This is helpful if your system chooses too small of a max heap size for the Java compiler during the bootstrap build.
