[PATCH v3] llvm/mesa/rust: simplify llvm-config handling

[Deepesh.Varatharajan]

From: Deepesh Varatharajan <Deepesh.Varatharajan@windriver.com>

Replace PATH-based llvm-config discovery with explicit sysroot-native
resolution and simplify the target llvm-config wrapper to act as a pure
pass-through while preserving Yocto alternate path handling.

The previous implementation relied on:

* `which -a llvm-config | sed -n 2p`
   which is unreliable in cross-build environments because it only
   searches executables present in $PATH. Native sysroot tools
   (e.g. recipe-sysroot-native llvm-config) are not guaranteed to be
   exposed via PATH, so they may not be discovered at all.

* `echo $base_libdir | sed -n '/lib64/p'`
   which depends on a BitBake variable that may be empty or unset
   in certain build contexts, leading to incorrect libdir selection.

Update the wrapper to:

* Use an @LLVM_CONFIG_PATH@ placeholder that is replaced during the
  build with the appropriate native llvm-config path.
* Detect libdir using filesystem inspection rather than variable
  parsing.
* Preserve `YOCTO_ALTERNATE_EXE_PATH` and
  `YOCTO_ALTERNATE_LIBDIR` handling.
* Delegate all arguments directly to the native llvm-config.

Update rust and mesa recipes to replace the placeholder with the native
llvm-config path during target and nativesdk builds.

Also remove the native llvm-config copy logic and lib/lib64 symlink
workarounds, relying instead on explicit native tool resolution.

We always configure PATH to contain the cross scripts and native
sysroot. Is there something which is reconfiguring PATH to skip the
native sysroot?

As I understand it, this is always being configured to point at the
llvm-config in the native sysroot?

I think this script is only ever installed into STAGING_BINDIR_CROSS?

If that is the case, could we just set this to a relative path to
SCRIPT_DIR, which would then always point at the right places without
needing to be adjusted each time?

Can you remind me, how does the native llvm-config provide the target
cflags? Is that triggered by setting the YOCTO_ALTERNATE_LIBDIR above?

After running bitbake rust -c devshell, I checked echo $PATH and seen native
sysroot path present there.

In this case, since we already know the exact location from which 
llvm-config should
be used, would it make sense to reference that path directly instead of 
recursively
searching for llvm-config from the current directory?

This script is used in both target and nativesdk builds, and the 
directory layout differs between them.
For example:

target : "../recipe-sysroot/usr/bin/crossscripts"
nativesdk : 
"../recipe-sysroot/usr/local/oe-sdk-hardcoded-buildpath/sysroots/x86_64-oesdk-linux/usr/bin/crossscripts"

Because the relative location of native llvm-config with respect to 
SCRIPT_DIR is not the same in these two environments,
a single path relative from SCRIPT_DIR would not resolve correctly in 
both cases. Therefore, the path cannot be expressed
as one fixed relative path and still work for both target and nativesdk 
builds.

Re: [PATCH v3] llvm/mesa/rust: simplify llvm-config handling

[Deepesh Varatharajan]

Hi Dmitry,

Yogesh has already posted a potential fix for this issue, and it is 
currently available in Mathieu's master-next branch.
https://git.openembedded.org/openembedded-core-contrib/commit/?h=mathieu/master-next&id=2e8ada1cb07d6dce8a0894b427b18b2bc585a2c8

I tested it locally, and it appears to resolve the issue. Could you 
please give it a try on your side and let us know if it
fixes the problem for you?

Regards,
Deepesh
