Description
After recent changes we're now seeing:
/__w/hpx/hpx/build/_deps/stdexec-src/include/stdexec/__detail/__spin_loop_pause.hpp:42:36: error: duplicate 'inline'
42 | STDEXEC_ATTRIBUTE(always_inline) inline void __spin_loop_pause() noexcept
| ^~~~~~
| ------
(see for instance: https://github.com/TheHPXProject/hpx/actions/runs/30292281413/job/90064638222?pr=7409)
This blocks two of our CIs, is there anything we can do to work around this issue?

Research direction
Start with stdexec/__detail/__spin_loop_pause.hpp at line 42 and reproduce the duplicate-inline error in the linked ARM CI job using GCC 11.4.0. Trace the recent changes that affect STDEXEC_ATTRIBUTE and determine a documented workaround or correction that lets both failing CI jobs compile successfully.
