No, I am still unable to cross-compile jdk8u for ppc32. I was able to get the latest community
ppc32 build from Azul, but it isn’t the latest/most up-to-date version.
I used to build PPC32 binaries for JDK 8u with debootstrapped sysroots and
native cross-compiler:

Found my old build scripts. Just did the following on https://github.com/openjdk/jdk8u-dev/, and it
worked.

=== 2. Debootstrap the sysroot: (you might be lucky with the sysroot you
already have)
https://github.com/openjdk/jdk/blob/master/doc/building.md#using-debian-debootstrap
=== 3. Configure with:
Assumes sysroot is at /chroots/powerpc/
$ CC=powerpc-linux-gnu-gcc CXX=powerpc-linux-gnu-g++ sh ./configure \
--openjdk-target=powerpc-linux-gnu \
--with-sysroot=/chroots/powerpc/ \
--x-libraries=/chroots/powerpc/usr/lib/powerpc-linux-gnu/ \
--with-freetype-lib=/chroots/powerpc/usr/lib/powerpc-linux-gnu/ \

--with-boot-jdk=/home/shade/jdks/8u/ \
--with-jvm-variants=zero \
--with-extra-cflags=-Wno-error
=== 4. Build with:
$ make images
=== 5. Enjoy:
