iucode-tool/host is used by intel-microcode to manipulate with microcode.bin file. iucode-tool requires cpuid.h at compile time for autodection feature, but non-x86 build hosts does not have this header file (e.g. ubuntu 20.04 aarch64) or this header generates compile time error (#error macro) (e.g. macos arm64). This patch provides compat cpuid.h to build iucode-tool/host on non-x86 linux hosts and macos. CPU autodectection is not required for intel-microcode package build so compat cpuid.h is ok for OpenWrt purposes. glibc and argp lib are not present in macos so iucode-tool/host build fails. This patch adds argp-standalone/host as build dependency if host os is macos. Generated ucode (intel-microcode package) is exactly the same on Linux x86_64 (Ubuntu 20.04), Linux aarch64 (Ubuntu 20.04) and Darwin arm64 (MacOS 11.6) build hosts. Signed-off-by: Sergey V.
