[libc] Fix using the `libcgpu.a` for NVPTX in non-LTO builds

CUDA requires a PTX feature to be compiled generally, because the
`libcgpu.a` archive contains LLVM-IR we need to have one present to
compile it. Currently, the wrapper fatbinary format we use to
incorporate these into single-source offloading languages has a special
option to provide this. Since this was not present in the builds, if the
user did not specify it via `-foffload-lto` it would not compile from
CUDA or OpenMP due to the missing PTX features. Fix this by passing it
to the packager invocation.

The LLVM Compiler Infrastructure

Welcome to the LLVM project!

This repository contains the source code for LLVM, a toolkit for the construction of highly optimized compilers, optimizers, and run-time environments.

The LLVM project has multiple components. The core of the project is itself called “LLVM”. This contains all of the tools, libraries, and header files needed to process intermediate representations and convert them into object files. Tools include an assembler, disassembler, bitcode analyzer, and bitcode optimizer.

C-like languages use the Clang frontend. This component compiles C, C++, Objective-C, and Objective-C++ code into LLVM bitcode -- and from there into object files, using LLVM.

Other components include: the libc++ C++ standard library, the LLD linker, and more.

Getting the Source Code and Building LLVM

Consult the Getting Started with LLVM page for information on building and running LLVM.

For information on how to contribute to the LLVM project, please take a look at the Contributing to LLVM guide.

Getting in touch

Join the LLVM Discourse forums, Discord chat, or #llvm IRC channel on OFTC.

The LLVM project has adopted a code of conduct for participants to all modes of communication within the project.
