make fails in tpcds-gen

[babaMar]

Compilation fails for me with:

/usr/bin/ld: s_purchase.o:/home/stefano/Repositories/hive-testbench/tpcds-gen/target/tools/s_purchase.c:55: multiple definition of `nItemIndex'; s_catalog_order.o:/home/stefano/Repositories/hive-testbench/tpcds-gen/target/tools/s_catalog_order.c:56: first defined here

collect2: error: ld returned 1 exit status

any clue?

Turns out the compiler is too new, had to use gcc 9, see gregrahn/tpcds-kit#57
