Gavin Hu c199ca1576 config: fix meson build on ThunderX2 
Since gcc-8.3(I tried 8.3 and 9.1), the meson build failed on ThunderX2.
It got the following compiling errors:
/usr/lib/gcc/aarch64-linux-gnu/9/include/arm_neon.h:26493:1: error:
inlining failed in call to always_inline ‘vmull_p64’:
target specific option mismatch 26493 | vmull_p64 (poly64_t a, poly64_t b)

Fixes: 7286c9d723 ("config: add thunderx2 machine")
