php8: missing PHP8_GETTEXT always depends on icu

[danielfdickinson]

Package Name

php8

Maintainer

@mhei

OpenWrt Version

SNAPSHOT

OpenWrt Target/Subtarget

bcm27xx/bcm2712

Steps to Reproduce

1. Select PHP8_GETTEXT but do not select php8-mod-gettext, php8-mod-intl, etc
2. Build php8

Actual Behaviour

Compile fails due to missing any icu variant

Solution: in Config.in select PACKAGE_icu in PHP8_GETTEXT definition

@mhei I noticed this while testing the tree-wide SDK build, but it is independent of that (so not fixing in that commit).
