Unable to build Client/Server variant for OpenJDK-11 on ARMv7-A

Hi,

This does not look a build issue per se, but rather a Hotspot bug.

This is an extremely old JDK 11 tree. The most actual one is here:
   https://github.com/openjdk/jdk11u-dev/

FWIW, ARM32 builds from that repo work for me on RPi 4:
   https://builds.shipilev.net/openjdk-jdk11-dev/

Additional things to try:
  *) Build fastdebug, trying to see if any VM assert is triggered; pass --with-debug-level=fastdebug 
to configure
  *) Build/test the JDK mainline (https://github.com/openjdk/jdk/), trying to see if this is a fixed 
issue that is missing a 11u backport
  *) Trim down --with-extra-cflags and --with-extra-cxxflags, looking for some special flag that 
triggers the bug

There were plenty of ARM32 bugs fixed (backported) in 11u, but I also see some that are only fixed 
in later JDKs, for example:
   https://bugs.openjdk.java.net/browse/JDK-8222825
