Building on armv7a with meson currenctly fails:
/usr/lib/gcc/arm-linux-gnueabihf/8/include/arm_neon.h:10369:1: error:
inlining failed in call to always_inline ‘vld1q_s32’: target
specific option mismatch
Set -mfpu=neon on that architecture like the legacy makefiles do to fix
the issue.
Fixes: b1d48c41189a ("build: support ARM with meson")
