[IMXRT1050-EVKB/uClinux| Building micropython

Hi, everybody,

I am using the nxp1050 evaluation board ( ... RT1050-EVK) and the emcraft uClinux build ( based on linux kernel version 4.5. The microcontroller/microprocessor is a 600Mhz cortex m7.
Compiler I am using is supplied by emcraft, the version is arm-v7-linux-uclibceabi-gcc (20170818-165657- build on build.emcraft by build) 4.7.4 20130508 (prerelease).

I have found a few posts saying that it is trivial to build for uClinux starting with the unix port (viewtopic.php?t=270) but I've ran into some problems and would appreciate some help.
Building a version of the same port for my local system works out of the box without a problem.

So, when I am running 'make deplibs' the build fails at building libffi
/RT1050/A2F/micropython/lib/libffi/src/arm/sysv.S: Assembler messages:
/RT1050/A2F/micropython/lib/libffi/src/arm/sysv.S:98: Error: selected processor does not support ARM opcodes
Makefile:1293: recipe for target 'src/arm/sysv.lo' failed

Any help would be appreciated.
