[ Upstream commitfde0ab43b9] There's a silly problem with the CC_HAS_ASM_GOTO_OUTPUT test: even with a working compiler it will fail on some architectures simply because it uses the mnemonic "jmp" for testing the inline asm. And as reported by Geert, not all architectures use that mnemonic, so the test fails spuriously on such platforms (including arm and riscv, but also several other architectures). This issue avoided any obvious test failures because the build still works thanks to falling back on the old non-asm-goto code, which just generates worse code. Just use an empty asm statement instead.
