In the buildlog I see

   13% tests passed, 228 tests failed out of 263

Errors seem to happen at OpenCL kernel build time:

   LLVM ERROR: unable to write nop sequence of 2 bytes

and mostly

   /usr/bin/ld: /lib/riscv64-linux-gnu/libm.so: can't link double-float
   modules with soft-float modules

   /usr/bin/ld: failed to merge target specific data of file
   /lib/riscv64-linux-gnu/libm.so

   /usr/bin/ld: /lib/riscv64-linux-gnu/libgcc_s.so.1: can't link double-float
   modules with soft-float modules

   /usr/bin/ld: failed to merge target specific data of file
   /lib/riscv64-linux-gnu/libgcc_s.so.1

   /usr/bin/ld: /lib/riscv64-linux-gnu/libc.so.6: can't link double-float
   modules with soft-float modules

   error: linker command failed with exit code 1 (use -v to see invocation)

   Final linking of kernel test_shuffle_2_2 failed.


I'd suggest postponing further analysis until sid has pocl 5.0 and
switched from llvm-15 to llvm-16. These two changes will *not* happen in
a single upload.
