# build_amsd.sh — meow_amsd 交叉编译（mipsel 静态）+ 宿主多目标可选。
#
# 目标：R3 Pro II / MeowOS（mipsel-linux-muslsf，静态）。amsd/am 极简仅 POSIX + Linux 基础接口
# + 复用 launcher 的 meow_ipc.h（-I../meow_launcherd），单文件即可固件内/usr/bin。
#
# 用法：
#   ./build_amsd.sh            # 交叉编译 → meow_amsd（mipsel 静态）
#   ./build_amsd.sh am         # 交叉编译 am CLI → am（mipsel 静态）
#   ./build_amsd.sh host       # 宿主编译 meow_amsd_host + am_host + ams_stub_host（集成测试）
