Only CPU_LDFLAGS is used in mk/rte.sharelib.mk.
It should be LDFLAGS to build the library with correct linkage options.

Does this continue to work on cross compiled arches (32 bit on 64 bit systems
and vice versa)?  I have this recollection that something in CPU_LDFLAGS was
needed

yes, LDFLAGS must contain CPU_LDFLAGS.

mk/target/generic/rte.vars.mk:# merge all LDFLAGS
mk/target/generic/rte.vars.mk:LDFLAGS := $(CPU_LDFLAGS) $(EXECENV_LDFLAGS) $(TOOLCHAIN_LDFLAGS) $(MACHINE_LDFLAGS)
mk/target/generic/rte.vars.mk:LDFLAGS += $(TARGET_LDFLAGS)
