The environment variables look wrong to me.
1. export 
CFLAGS="--sysroot=/opt/poky/1.5+gst/sysroots/x86_64-linux/usr/bin/cortexa9-vfp-neon-poky-linux-gnueabi" 
: sysroot is not supposed to point to the cross compiler directory, but 
to the sysroot of the *device* (same goes for the LDFLAGS, the 
PKG_CONFIG_SYSROOT_DIR, and the kernel headers path)
2. the "/build" part of the kernel headers path needs to be removed
3. do you use hardfloat or softfloat? In one place, you use cortexa9, in 
another, cortexa9hf

I attached an example script that may be clearer (at successfully builds 
the plugins). It builds for the Sabre SD DualLite platform.

cheers
