BAD NEWS: remove mips support

[nxhack]

Upstream of node.js, support for mips seems to be removed in the future. I plan to maintain mips as much as possible but may not be able to do so depending on the circumstances.

nodejs/node#26179
nodejs/node#26192

[nxhack]

The mips support has been removed in v12.0.0.
I'm reverting the deleted codes.

how can you are saying nodejs 12 dropped mips, i just built mt7621 (ramips):
https://cdn.corifeus.com/openwrt/18.06.3/packages/mipsel_24kc/node/

and it works. how come it still works?

[p3x-robot]

ok, got it you have the patches for mips. thanks

[nxhack]

The cross compilation environment is broken in v12.5.0.
The situation is difficult.

[p3x-robot]

ok, i am happy, that i am buying a new linksys wrt32x, because i will not use the d-link dir 860d b1 anymore, it looks like the last was in nodejs 12.4.0 for the ramips build....

[p3x-robot]

that is why you reverted to 12.4.0?

[nxhack]

@p3x-robot
As it was likely to take time to support v12.5.0, I made a dedicated branch. For that purpose, I restored the master branch and the development branch.
It is the latest version that v12.4.0 is supported.

build: add mips64el support

nodejs/node#27992

[p3x-robot]

so it will still not support ramips mt7621 , right?

[p3x-robot]

it is only for mipsel64 i suppose.

[nxhack]

Exactly.
mips32 will not be considered much.
I will try my best as much as possible.

[nxhack]

After V8-v7.9, mips(eb) and mips64(eb) will not work.

I successfully compiled nodejs v10 for mipsel_24kc (newifi D2).
But the only problem I have right now is it's really slow. CPU and ram consumptions are at less than 50% only. Simple http ajax request, express response at 5-6 seconds.

[nxhack]

Verified with version 14.12.0. Unfortunately, I confirmed that it does not work on mips(eb) and mips64(eb).
