My colleague Marina Polyakova <m.polyakova@postgrespro.ru> found
the similar bug on buildfarm [1] for REL_15_STABLE in the llvm build:

  -D_GNU_SOURCE -I/usr/include/libxml2  -flto=thin -emit-llvm -c -o segparse.bc segparse.c
segparse.y:177:10: fatal error: 'segscan.c' file not found
   177 | #include "segscan.c"
       |          ^~~~~~~~~~~
1 error generated

Maybe backpatch [2] to all supported versions not just 16+?
  

With the best regards,
