Comment:
Thank you so much for your help so far on this, @classabbyamp.

I tried applying the patch you suggested on IRC (https://github.com/LinearTapeFileSystem/ltfs/commit/2db929b5fc641fbeccb06ba38b3c7e3d4f25a86c).
It no longer works with the current `configure.ac`, so I modified it slightly:

Unfortunately, this still results in the same error.
I did also try without removing the whole `if` statement around the assignment of `ICU_MODULE_VERSION`, but the result was the same.

Would it be possible to make it so that this package gets built in qemu, rather than cross-compiling?
It might just be a simpler way out.
