Meson crosscompiling fail on compiling error

[kochmmi1]

Hi all,
i am trying to build a newer version of gstreamer and gstreamer-plugins-good for my tynirex platform (https://www.voipac.com/#iMX6-TRM-23632311) running linux (Jan  1 (Linux version 3.14.58-02398-g4f1acce-dirty
 CPU: ARMv7 Processor [412fc09a] revision 10 (ARMv7), cr=10c53c7d ). I'd like to avoid re-building the sysroot and buildroot entirely. I am building on an ubuntu and I have the sysroot against which I have succesfully built several applications. In this sysroot (and on the host itself) is an old version of gstreamer i would like to replace.

I run $ meson --cross-file cross_spec.txt with some "NO"s, but no error. Here is the meson log and crossfile.

Running the subsequent ninja command crashes on compiling error:

Basically the same error repeats itself for several files, the compile output ends with 'ninja: build stopped: subcommand failed.'

 I am assuming that I do not have some path set reagarding the crosscompilation - can someone point to me what I am missing? Thanks.
