-This test checks that a pre-existing object file can be used in projects.
-In order to do this, we need prebuilt objects in the source dir. To enable
-a new platform, the source file source.c needs to be compiled and then
-the Meson file updated to use it.
-
-The object needs to be built with no optimization and debug symbols enabled.
-As an example, this is what a compile command with Gcc on x86 Linux would
-look like:

-gcc -c -g -o linux-i386.o source.c
