node: Raspberry Pi3 / brcm2710 errors due to CPU/arch

[plntyk]

nodejs has multiple build issues see #3056 , argument list too long due to internal openssl (see imyller/meta-nodejs#9 ) and multiple CPU support issues like this one:

brcm2710 (Raspberry Pi-3) is armv8-a
other ones Raspis (brcm2709/brcm2708) are armv7-a

-mpcu=cortex-a53 emits ARM_ARCH 8

armv8-a is NOT supported by internal deps/v8 in v4.x in nodejs
upstream commit is : v8/v8@1d14ebf

possible solutions:

• disable nodejs on brcm2710
• use armv7-a for brcm2710 / change include/target.mk
• update nodejs from LTS to next LTS v6 (6.x) , see https://github.com/nodejs/LTS#lts_schedule
• reported on IRC & replicated locally

Close this since the node v6.11.2 in the repo now has a v8 with armv8-a support.
