Thank you, I have adjusted my setup accordingly.

Thank you for pointing me in the right direction! I have found the
solution. Originally, on my device I had installed the "libc6-dev"
package because it contained various object files (crti.o, for
example) that FPC needed to link. After I copied the contents of
/usr/lib and /lib to my cross-compile build VM, I removed the package
from my device to conserve disk space.

The file "libdl.a" was included in this libc6-dev package, so I had
copied it over to my build vm. However, on a whim I moved the file
into the trash and tried compiling again. The compiler complained
about not being able to find libdl, so I put a symlink for libdl.so.2
as libdl.so and then it compiled fine, and ran correctly as well once
I copied it to the target device. So apparently having that libdl.a
around was confusing things.

Thanks again for your help.
