Does debian disable dynamic GHC by default as `DYNAMIC_GHC_PROGRAMS = NO`?
No (`ldd /usr/lib/ghc/bin/ghc` lists various `libHS...` libraries). Are you using secure PLT? This might be done as part of hardening.
In the ABI specs p 108 relocations {{{R_PPC_REL16*}}}: ''These relocation types are used to compute the distance between a symbol address and the current address. These relocations types are used under the '''Secure-PLT ABI''' to compute the address of the .got section because the link editor knows the fixed distance between the _GLOBAL_OFFSET_TABLE_ symbol and an address in the .text section.''
