  rts/linker: Don't fail due to RTLD_NOW
  
  In !12264 we started using the NativeObj machinery introduced some time
  ago for loading of shared objects. One of the side-effects of this
  change is shared objects are now loaded eagerly (i.e. with `RTLD_NOW`).
  This is needed by NativeObj to ensure full visibility of the mappings of
  the loaded object, which is in turn needed for safe shared object
  unloading.
  
  Unfortunately, this change subtly regressed, causing compilation
  failures in some programs. Specifically, shared objects which refer to
  undefined symbols (e.g. which may be usually provided by either the
  executable image or libraries loaded via `dlopen`) will fail to load
  with eager binding. This is problematic as GHC loads all package
  dependencies while, e.g., evaluating TemplateHaskell splices. This
  results in compilation failures in programs depending upon (but not
  using at compile-time) packages with undefined symbol references.
  
  To mitigate this NativeObj now first attempts to load an object via
  eager binding, reverting to lazy binding (and disabling unloading) on
  failure.
  
  See Note [Don't fail due to RTLD_NOW].
  
  Fixes #25943.

  Revert "ci: re-enable chrome for wasm ghci browser tests"
  
  This reverts commit fee9b351fa5a35d5778d1252789eacaaf5663ae8.
  Unfortunately the chrome test jobs may still timeout on certain
  runners (e.g. OpenCape) for unknown reasons.
