sharp: Can't install on linux/arm64 with docker node

Trying to run a simple Dockerfile to install node together with sharp on linux/arm64 fails.

FROM node:14-slim

RUN npm i detect-libc

RUN node -e "console.log('platform=' + process.platform);console.log('arch='+process.arch);console.log(require('detect-libc'))"

RUN npm i sharp

when ran on arm64 - it produces:

> [4/4] RUN npm i sharp:

while the arch checks gives:

platform=linux
arch=arm64
{
  GLIBC: 'glibc',
  MUSL: 'musl',
  family: 'glibc',
  version: '2.24',
  method: 'getconf',
  isNonGlibcLinux: false
}

There are already prebuild libvips images for arm64v8 - why aren’t they used?

Running the same on Windows 10, goes actually just fine. While the arch checks is there pretty much the same:

@lovell I think the glibc check is a bit too hard and doesn’t check for prebuild images first.
