Bug description

I'm building ocaml in Alpine Linux ppc64le and it builds fine. But when I try to use ocamlc, I'm getting a segfault.

Gdb backtrace shows:

#0 0x00003fffb7fad710 in do_relocs (dso=0x3fffb7ff26a0 , rel=0x200ab4b8, rel_size=2495088,

I know that ocaml was recently ported to ppc64le architecture and works fine with glic, but seems there is an issue with musl.

Steps to reproduce

The steps bellow need to be done inside an Alpine ppc64le:

• Clone aports repository
  $ git clone https://github.com/alpinelinux/aports.git

• Build ocaml package
  $ cd aports/community/ocaml
  $ abuild -r

• Install the built package:
  $ sudo apk add <ocaml_apk>

• Run ocamlc to get the segmentation fault.
