[3uclid3]

Xmake Version

2.9.3+20240723

Operating System Version and Architecture

Kubuntu 24.04

Describe Bug

The pkgtest fail if warning as error are enabled in a custom toolchains.

Expected Behavior

Test must not fail if warning as error are enabled.

The test should look like that to ensure that 'test' method does NOT return
HEDLEY_NO_RETURN void test() { std::abort(); }
