Can you run following command:
 /home/marco/dev/buildroot/output/host/usr/bin/arm-fsl-linux-gnueabi-gcc
-print-file-name=crt1.o
and verify that the reported file exists? What is the output?

Normally you shouldn't give any special environment flags.

You could also try to compile a simple hello world program with that
compiler in output/host/usr/bin, to see if that works correctly or
not.

Thanks,
Thomas
