The fix from JDK-8246112 breaks the build with old (but according to comments still supported) glibc versions, when ld defaults to the --as-needed behavior.

The reason for that is the passing of a library (-lrt) in a LDFLAGS macro, not in a LIBS macro.

A quick workaround is

--- a/make/autoconf/flags-ldflags.m4
+++ b/make/autoconf/flags-ldflags.m4

- OS_LDFLAGS_JVM_ONLY="-lrt"

So -lrt should be passed in the macros which are used to pass -ldl -lpthread ...
