+Upstream-Status: To upstream [not yet submitted; pdfium main's skia/BUILD.gn still lacks the riscv64 branch Chromium's copy has]
+
+PDFium's skia/BUILD.gn asserts on every target CPU its skia_opts chain does not
+name, so `gn gen` fails for target_cpu = "riscv64" even with pdf_use_skia=false:
+the root BUILD.gn's gn_check group depends on //skia whenever checkout_skia is set,
+which it is for checkout_configuration=small. Chromium's own skia/BUILD.gn already
+carries this empty riscv64 branch (Skia's portable code path needs no extra flags).
