Revert "[Libomptarget] Make the plugins ingore undefined exported symbols"
This reverts commit 3f62314c235bd2475c8e2b5b874b2932a444e823.
Revert "[LLD] Enable --no-undefined-version by default."
This reverts commit 7ec8b0d162e354c703f5390784287054601f9c69.
Three commits are reverted because of the current omp build fail
with GNU ld. See discussion here: https://reviews.llvm.org/rG096f93e73dc3
Summary:
Recent changes made the default behaviour to error when given an
undefined symbol in a version script. A previous patch fixed this for
`libomptarget` by removing the single undefined symbol. However, the
plguins are expected to only define a subset of the availible functions
so we shouldn't treat it as an error. This patch updates the build flags
to work appropriately.
The remote offloading server and plugin rely on OpenMP, so this needs to be added as a linker flag. Without this, applications segfault.

This fixes a compile-time error recently introduced within the remote
offloading plugin. This patch also removes some extra linker flags that are unnecessary, and adds an explicit abseil linker flag without which we occasionally get problems.

D97883 introduced a compile-time error in the experimental remote offloading
libomptarget plugin, this patch fixes it and resolves a number of
inconsistencies in the plugin as well:
1. Non-functional Asynchronous API
2. Unnecessarily verbose debug printing
3. Misc. code clean ups
This is not intended to make any functional changes to the plugin.

This change-set removes libelf usage from elf_common part of the plugins.
libelf is still used in x86_64 generic plugin code and in some plugins
(e.g. amdgpu) - these will have to be cleaned up in separate checkins.

This introduces a remote offloading plugin for libomptarget. This
implementation relies on gRPC and protobuf, so this library will only
build if both libraries are available on the system. The corresponding
server is compiled to `openmp-offloading-server`.
This is a large change, but the only way to split this up is into RTL/server
but I fear that could introduce an inconsistency amongst them.
Ideally, tests for this should be added to the current ones that but that is
problematic for at least one reason. Given that libomptarget registers plugin
on a first-come-first-serve basis, if we wanted to offload onto a local x86
through a different process, then we'd have to either re-order the plugin list
in `rtl.cpp` (which is what I did locally for testing) or find a better
solution for runtime plugin registration in libomptarget.
