[Buildroot] [PATCH 1/1] package/nodejs: use system-icu for host-nodejs when available

James, All,

Pointing to an autobuild failure is nice, but you really need to provide
a bit more context and explanations on what you are doing here...

We already have a conditional block about icu, lines 35-40.

Why do you need to account for a target package when building the host
variant of nodejs? If this is needed, then explain it in the commit log.

Then, the way we usually pass such options is to append to the existing
CXXFLAGS. With the above comment, that would probably yield something
like (e.g. for target, ditto for host):

    NODEJS_CXXFLAGS = $(TARGET_CXXFLAGS)

    ifeq ($(BR2_PACKAGE_ICU),y)
    NODEJS_DEPENDENCIES += icu
    NODEJS_CONF_OPTS += --with-intl=system-icu
    NODEJS_CXXFLAGS += -DU_DISABLE_RENAMING=1
    else
    NODEJS_CONF_OPTS += --with-intl=small-icu
    endif

    [...]

    $(TARGET_MAKE_ENV) PYTHON=$(HOST_DIR)/bin/python2 \
        $(MAKE) -C $(@D) \
        $(TARGET_CONFIGURE_OPTS) \
        CXXFLAGS="$(NODEJS_CXXFLAGS)" \
        [...]
