After pulseaudio upgrades from 13.0 to 14.0, it also switches from autotools
to meson. In autotools, there is --disable-neon-opt option for disabling NEON
optimizations, but there is no counterpart in meson.
And the meson build system adds -mfpu=neon at the end of the compiler command
line which overrids any earlier -mfpu options and result below build failure
on armv5:

Define -mfloat-abi=softfp for CC on armv5 to fix the above issue.
