Re: [OE-core] [PATCH v2] gcc: remove paths to sysroot from configargs.h and checksum-options for gcc-cross-canadian

[Denys Dmytriyenko <denis@denix.org>]

FWIW, I'm testing master-next now with your patch applied and I'm also seeing 
the same buildpaths QA error in .../include-fixed/pthread.h

ERROR: gcc-cross-canadian-aarch64-14.1.0-r0 do_package_qa: QA Issue: File /usr/local/oe-sdk-hardcoded-buildpath/sysroots/x86_64-pokysdk-linux/usr/lib/aarch64-poky-linux/gcc/aarch64-poky-linux/14.1.0/include-fixed/pthread.h in package gcc-cross-canadian-aarch64 contains reference to TMPDIR [buildpaths]
ERROR: gcc-cross-canadian-aarch64-14.1.0-r0 do_package_qa: Fatal QA errors were found, failing task.
ERROR: Logfile of failure stored in: /OE/poky-master/build/tmp/work/x86_64-nativesdk-pokysdk-linux/gcc-cross-canadian-aarch64/14.1.0/temp/log.do_package_qa.820539
ERROR: Task (/OE/poky-master/meta/recipes-devtools/gcc/gcc-cross-canadian_14.1.bb:do_package_qa) failed with exit code '1'

The header file contains this:

/*  DO NOT EDIT THIS FILE.

    It has been auto-edited by fixincludes from:

        "/OE/poky-master/build/tmp/work/x86_64-nativesdk-pokysdk-linux/gcc-cross-canadian-aarch64/14.1.0/recipe-sysroot/usr/include/pthread.h"

    This had to be done to correct non-standard usages in the
    original, manufacturer supplied header file.  */

Both gcc-target and gcc-cross end up removing this header file:
https://git.openembedded.org/openembedded-core/commit/?id=e0af4b2c8f8e29ac6f8eccef401c7c004355359d
https://git.openembedded.org/openembedded-core/commit/?id=f0fcaa88b7b2977c2cb35b060747442ee9ff3dcd

I'm not sure if we should do the same for gcc-cross-canadian as well - I'm 
trying it locally now...
