gnu-libiconv-1.16 doesn't work with php8

[joepagan]

As I highlighted in this comment on the issue: gnu-libiconv-1.16 does not work with php:8.0-fpm-alpine.
It installs ok and appears in the php info, though the errors I get are as if it is not installed.

The highly up voted answers in the linked issue specifically reference the edge CDN: http://dl-cdn.alpinelinux.org/alpine/edge/community where only libiconv-1.16 is available. Instead, for php8 we have to use the CDN for alpine v3.13 (despite being on alpine which is currently v3.14) to get access to gnu-libiconv=1.15-r3 which does load successfully and work with php8.

On another point, I do feel that the original issue should be re-opened as this seems like the work around in the original issue is a hack which we shouldn't need to do, though I appreciate that issue requires changes further up the chain at the alpine level to resolve.

Hey @joepagan! I'm not sure what the official image project can do if there's a problem upstream with Alpine. Can you close this and reopen it when there's something actionable?

[wglambert]

Closing given what was said in #240 (comment)

There isn't really anything actionable we could do at the Dockerfile level to alleviate this

Yes that's fair to close, sorry for the noise and for inactivity had some stuff going on. Now coming back to it I think it's more of an bug for php themselves to look at.
