[meta-clang][PATCH] conf/nonclangable.conf: Always build mesa with gcc

[Böszörményi Zoltán]

Building mesa (at least version 19.3.4) with clang 9.0.1 leads
to linker errors on x86/x86-64:

"undefined reference to `typeinfo for llvm::raw_pwrite_stream'"
in libvulkan_radeon.so

and

"undefined reference to `typeinfo for llvm::RTDyldMemoryManager'"
in libgallium.a.

It was reported at https://gitlab.freedesktop.org/mesa/mesa/issues/2533

It seems it is related to rtti not being enabled, at least reports
from a few years ago on forums lead to that conclusion.
But enabling rtti for clang in PACKAGECONFIG doesn't help.

Just build mesa with gcc, it fixes the linker errors.

Ignore this, the patch is against the zeus branch.
Re-sent with the proper subject.

== Summary ==


Thank you for submitting this patch series to OpenEmbedded Core. This is
an automated response. Several tests have been executed on the proposed
series by patchtest resulting in the following failures:



* Patch            [meta-clang] conf/nonclangable.conf: Always build mesa with gcc
 Issue             Series sent to the wrong mailing list [test_target_mailing_list] 
  Suggested fix    Check the project's README (meta-clang) and send the patch to the indicated list

* Issue             Series does not apply on top of target branch [test_series_merge_on_head] 
  Suggested fix    Rebase your series on top of targeted branch
  Targeted branch  master (currently at 23ad05b98a)



If you believe any of these test results are incorrect, please reply to the
mailing list (openembedded-core@lists.openembedded.org) raising your concerns.
Otherwise we would appreciate you correcting the issues and submitting a new
version of the patchset if applicable. Please ensure you add/increment the
version number when sending the new version (i.e. [PATCH] -> [PATCH v2] ->
[PATCH v3] -> ...).
