meson: fix nativesdk-meson for multilib SDKs
Multilib SDKs differ only in the environment variables set, so nativesdk-meson's setup script needs to write a cross file for each environment. Rename the shipped meson.cross to meson.cross.template, as it cannot be used directly. Now that post-relocate scripts are called once for each environment, the generated meson.cross can be prefixed with TARGET_PREFIX to ensure it is unique. Finally rewrite the setup script to use string.Template to perform the expansion instead of hand-coding the logic. (From OE-Core rev: 8596f871ef834a38e3375443f7eb08e43816347a) Signed-off-by: Ross Burton <ross.burton@intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
