Typelib files are essentially a memory dump of internal g-i C structures 
to disk. They might be the same on every architecture, or they might not 
(endiannness, alignment). I'm not trusting that they are. So to produce 
them for target we build a target g-ir-compiler and run it under qemu.

In this case, the produced typelib files are not intended for the 
target, they are intended for the nativesdk package. The error is 
probably some simple mismatch between the binary name and what the build 
configuration expects to run. I have a hunch that's not the only issue 
to sort though :)
