With my latest small pushes to build-infra/jdk8-hotspot-jdk the build-infra forest can successfully cross compile from 32bit-linux to 64bit-linux and vice versa.
Some of the final problems were to set HOSTCC,HOST_CC and NIO_CC to be the compiler that compiles code for the build platform.
Strip away the ARCHFLAG from the CFLAGS and LDFLAGS when building the adlc tool.
And finally, navigate through the minefield of the strings: i386,i486,i586,i686,amd64 and x86_64 that are used in the hotspot makefiles, to get docs in the right dir when cross compiling.
../autoconf/configure --host=x86_64-unknown-linux-gnu --with-builddeps-conf=/localdisk/yourdir/jdk8/common/autoconf/builddeps.conf.example --with-builddeps-server=buildtools.se.oracle.com/buildtools/openjdk --with-builddeps-dir=/localdisk/yourdir/builddeps --with-jvm-variants=server
../autoconf/configure --host=i686-unknown-linux-gnu --with-builddeps-conf=/localdisk/yourdir/jdk8/common/autoconf/builddeps.conf.example --with-builddeps-server=buildtools.se.oracle.com/buildtools/openjdk --with-builddeps-dir=/localdisk/yourdir/builddeps --with-jvm-variants=server
For those outside of oracle, it should work without builddeps as long as you have created a cross-compiler toolchain like i686-unknown-linux-gnu-gcc et al and put it in the path and supplied a correct sys-root with the configure option --with-sys-root=....
