At this point sorry to be a pain :) but the LDFLAGS are a mess...  What about
this, it's much simpler:

# Note that we intentionally override the bindir supplied by ACX_LT_HOST_FLAGS
liblto_plugin_la_LDFLAGS = $(lt_host_flags) -bindir $(libexecsubdir)

# This can go away if libiberty becomes a libtool convenience library.
liblto_plugin_la_DEPENDENCIES = $(if $(wildcard ../libiberty/pic/libiberty.a), \
	../libiberty/pic/libiberty.a,../libiberty/libiberty.a)
liblto_plugin_la_LIBADD = \
	-Wc,$(liblto_plugin_la_DEPENDENCIES)
