Subject: [PULL 8/9] tcg/ppc: Ensure _CALL_SYSV is set for 32-bit ELF
Date: Sun, 12 Sep 2021 08:58:08 -0700	[thread overview]
Message-ID: <20210912155809.196236-9-richard.henderson@linaro.org> (raw)
In-Reply-To: <20210912155809.196236-1-richard.henderson@linaro.org>

Clang only sets _CALL_ELF for ppc64, and nothing at all to specify
the ABI for ppc32.  Make a good guess based on other symbols.
