 GHCi cannot handle ELF symbols with relocation types 15 (i386) and 22
 (amd64) (such as {{{ThreadRuneLocale}}}, coming from libc on systems later
 than 9.0) when dynamically loading object files.

 This can be reproduced by the issuing the following commands:

 {{{
 # pkg install hs-hs-bibutils
 ..
 $ ghci
 Prelude> :m Text.Bibutils
 Prelude> bibl_init
 Loading package syb-0.4.0 ... linking ... done.
 Loading package hs-bibutils-5.0 ... linking ... <interactive>:
 /usr/local/lib/cabal/ghc-7.6.3/hs-bibutils-5.0/HShs-bibutils-5.0.o:
 unhandled ELF relocation(Rel) type 15
 ghc: unable to load package `hs-bibutils-5.0'
 Prelude>
 }}}

 The source file {{{rts/Linker.c}}}, function
 {{{do_Elf_Rela_relocations()}}} is missing the case branches for types 15
 ({{{R_386_TLS_IE}}}) and 22 ({{{R_X86_64_GOTTPOFF}}}). They shall be
 implemented for FreeBSD.
