No need to respin just for that.

Well, CXXFLAGS are set in $(HOST_CONFIGURE_OPTS):

    $ make printvars VARS=HOST_CONFIGURE_OPTS RAW_VARS=YES
    [...] CXXFLAGS="$(HOST_CXXFLAGS)" [...]

So, were they used previously? If not, then the commit log should say
so.

However, I'm afraid they were. They at least contain the CFLAGS, which
contain the optimisation level (-O2), but mnost importantly, contain the
CPPFGLAGS, so contains the correct include path to $(HOST_DIR)/include

And it seems the default value for CXXFLAGS.target does use CXXFLAGS:

    tools/gyp/pylib/gyp/generator/make.py:CXXFLAGS.target ?= $(CPPFLAGS) $(CXXFLAGS)

So maybe we need something like:

    HOST_NODEJS_CXXFLAGS = $(HOST_CXXFLAGS) -DU_DISABLE_RENAMING=1

and in the configure and build comands:

    ...
    $(HOST_CONFIGURE_OPTS) \
    CXXFLAGS="$(HOST_NODEJS_CXXFLAGS)" \
    ...

Yann E. MORIN.
