Commit 24d90db52a74 (package/nodejs: disable icu support for host build)
added --with-intl=none to host configure flags to fix an issue related to
icu.  The 0.10.x version unfortunately doesn't understand this configure
flag and errors out when provided, breaking the build:

configure: error: no such option: --with-intl

The 0.10.x version doesn't seem to have this icu issue (E.G. no autobuilder
issues before this commit and unable to reproduce locally), so fix it by
only passing --with-intl=none for the 6.9.x version.
