Seems like cc is being used instead of the cross-compiler/linker.

Did you use the meson-package mechanism in Buildroot? c.f.
https://buildroot.org/downloads/manual/manual.html#_infrastructure_for_meson_based_packages

This should have everything required to compile meson packages. Define
only the variables that are required and add one by one optional
variables until you get it to build.

Having the actual package makefile for your casync package would help a
lot if it still does not work.

Cheers,
Quentin
