linux 64-bit compilation requires -Wno-error

seems similar to
Bug 654996: use target-specific variable to disable -Werror in these cases

https://bugzilla.mozilla.org/show_bug.cgi?id=654996

so in core/manifest.mk we do
----
ifeq (x86_64,$(TARGET_CPU))
ifeq ($(TARGET_OS),linux)
$(curdir)/AvmCore.$(OBJ_SUFFIX): avmplus_CXXFLAGS += -Wno-error
$(curdir)/CodegenLIR.$(OBJ_SUFFIX): avmplus_CXXFLAGS += -Wno-error -fpermissive
$(curdir)/exec-jit.$(OBJ_SUFFIX): avmplus_CXXFLAGS += -Wno-error
$(curdir)/exec-osr.$(OBJ_SUFFIX): avmplus_CXXFLAGS += -Wno-error
$(curdir)/InvokerCompiler.$(OBJ_SUFFIX): avmplus_CXXFLAGS += -Wno-error
$(curdir)/LirHelper.$(OBJ_SUFFIX): avmplus_CXXFLAGS += -Wno-error
$(curdir)/PoolObject.$(OBJ_SUFFIX): avmplus_CXXFLAGS += -Wno-error
endif
endif
----

and here the real problem

- fixing bug in our source code, it's OK
- going into the AVM2 source code to fix such bugs is possible but not wanted
