syslinux: rewrite recipe so only target code is x86-specific
Currently the syslinux recipe set COMPATIBLE_HOST to 32/64-bit x86. Whilst this makes sense for the target binaries as syslinux is x86-specific, this also affects the native recipe which should be able to be built on non-x86 build hosts (for example, arm64 build host, qemux86 target). syslinux itself has a somewhat fragile build system but with care it is possible to build the installer for native/nativesdk, and the bootloader for target.
