libvpx: fix VPXTARGET for non-neon armv7a

The compiler might use non-supported instructions, as the build config
requires armv7-linux-gcc targets to have NEON[1] and drops the mtune
value[2], which also might use d32 registers on d16 cpus.

Falling back to the generic-gnu target respects the toolchain-set values
and should therefore be used instead.
