Compiling mruby for STM32F407 target of cerebral cortex

I am trying to compile mruby for the STM32F407 cortex-m4 target, but when run ./minirake

in the repo directory I get the following error:

Command Failed: ["/home/eugenio/gcc-arm-none-eabi-4_7-2012q4/bin/arm-none-eabi-ld" 
 -T "/home/eugenio/gcc-arm-none-eabi-4_7-2012q4/share/gcc-arm-none-eabi/samples/ldscripts/mem.ld" 
 -o "build/arm-none-eabi/bin/mrbc" 
 "build/arm-none-eabi/tools/mrbc/mrbc.o" 
 "build/arm-none-eabi/lib/libmruby_core.a" ]`

      

        
        
        
      

    

What am I doing wrong? The toolchain is the one from the git repo launcher updated, and googling it didn't help.

The build_config file for mruby is in buildconfig
