Ah, this might be because you're not building with --disable-warnings-as-errors
which I always use. I always build with:

sh ./configure --with-jvm-variants=zero --with-boot-jdk=/usr/lib/jvm/java-9-openjdk-amd64/ --disable-precompiled-headers --disable-warnings-as-errors && make
JOBS=32 MAKE_VERBOSE=y QUIETLY= LOG=debug CONF=linux-x86_64-normal-zero-release

which is the same configure line that the openjdk-7/8/9/10 packages in Debian
use. Sounds like a good idea to fix this warning though.

I assume that you eventually want to build OpenJDK for MIPS, correct (from your
email address)? If yes, there are actually two additional patches necessary to
get Zero to build on MIPS. In particular, jvmsigs cannot encode all signals
found on MIPS. I should finally get around to work on this.
