If this is related to yesterday's similar query [0], then I assume
you're using http://hg.openjdk.java.net/jdk8u/jdk8u/ for the build.
There is no dedicated ARM port in JDK 8u. You would need to build the
Zero interpreter instead, if you are building from the forest above, or,
as Andrew suggested, use a different forest from the AArch64 Port Project.

Hi all,
We've been putting together a community build farm and have wrangled from
ARM machines. We are building from jdk8u and have the following
configuration:

Configured the JDK
------
We notice that the configure output states:
checking if the C compiler supports "-m64"... no
checking if the C++ compiler supports "-m64"... no
checking if both compilers support "-m64"... no
checking if the C compiler supports "-m64"... no
checking if the C++ compiler supports "-m64"... no
checking if both compilers support "-m64"... no

The hotspot build then fails (predictably enough) at:
CCACHE_COMPRESS=1 CCACHE_SLOPPINESS=time_macros /usr/local/bin/ccache
/usr/bin/g++-5 -DLINUX -D_GNU_SOURCE -DAMD64 -DPRODUCT -I.

We're inexperienced at build on this architecture, I assuming that we
either need a compiler that supports -m64 or that -m64 should not be passed
through in this case?
