[PATCH v2 0/6] MR2347: Various fixes for dbghelp's ELF integration.

[eric pouech (＠epo)]

This series fixes a couple of issues related to dbghelp lookup in ELF
modules:
- get the correct wine loader in 64bit multi-arch setup
- don't fail in 32bit multi-arch setup when trying to access 64bit ELF
  modules above 4G
- handle libwine.so removal and let vdso lookup work again
- adding a couple of tests

--
  v2: dbghelp: Fix vdso.so lookup.
      dbghelp: Don't set ELF loader when wine's loader isn't accessible.
      dbghelp/tests: Add tests for SymRefreshModuleList() on non-live target.
      dbghelp: Use 'wine' as loader on multi-arch configuration.
      dbghelp/tests: Preserve last error in process_get_kind().
      dbghelp/tests: Better use global variables.
