Undefined symbols in libjvm.so is no good, and it should not be allowed.
However, I am unsure about your analysis. This flag only affect linking
of executables, not shared libraries. We do set "-Wl,-z,defs" when
linking shared libraries, and this should complain about undefined symbols.

Hi,
I have recently encountered bugs caused by undefined symbols in
libjvm.so[1][2]. The root cause of those issues is the expression in
make/autoconf/flags-ldflags.m4:
---
if test "x$TOOLCHAIN_TYPE" = xgcc; then
EXECUTABLE_LDFLAGS="$EXECUTABLE_LDFLAGS -Wl,--allow-shlib-undefined"
...

OpenJDK master builds fine after fixing[1] on the following
architectures: amd64, i386, armhf, arm64, s390, ppc64el and riscv64.
Would it be possible to consider removing -Wl,--allow-shlib-undefined
from the build flags?
Best Regards,
Vladimir.
