# build_sysui.sh — meow_sysui 交叉编译（mipsel 静态）+ 宿主编译可选。
#
# 目标：R3 Pro II / MeowOS（mipsel-linux-muslsf，静态）。sysui 极简无外部依赖，
# 仅 POSIX + Linux 基础接口（同 svcd），单文件满足「固件内、不入卡」。
#
# 用法：
#   ./build_sysui.sh           # 交叉编译 → patch_v2/meow_sysui/meow_sysui（mipsel 静态）
#   ./build_sysui.sh host      # 宿主编译 → patch_v2/meow_sysui/meow_sysui_host（集成测试用）
