Initial investigation, bug still applies for Ubuntu 26.04 LTS (libamd-
comgr3 7.1.1+dfsg-0ubuntu1):
Running test on a fresh install:
```
$ sudo apt install -y rocm-opencl-icd libamd-comgr3 clblast-tests
$ /usr/bin/clblast_test_xgemmbatched
CLBlast: OpenCL error: clBuildProgram: -11

-platform 0 [=default]
-device 0 [=default]
-full_test [false]
-verbose [false]
-cblas 1 [=default]
* Running on OpenCL device 'Radeon 8060S Graphics'.
* Starting tests for the 'SGEMMBATCHED' routine. Legend:
