[OpenMP] Stub vprintf on non-NVPTX if no libc (#180025)

sarnex · web-flow · commit 02d8c9c63a99 · 2026-02-05T22:11:32.000Z
The AMDGPU check was added in #123670 where the reasoning seems to be that the NVIDIA SDK will provide `vprintf` for the NVPTX case and AMDGPU was the only other supported target at the time. SPIR-V also needs this stubbed out, so just check that it's not NVPTX. Signed-off-by: Nick Sarnie <nick.sarnie@intel.com>
