Makefile.x86 in ubuntu 1604 Vivado 2017.2

Bad version of gcc?
I have created a Ubuntu 1604 using VirtualBox on a Windows10 machine, and installed Vivado HLx 2017.2 webpack.

When running Makefile.x86, an error terminated the run:
-------------- snip -------------
#
# configuration written to .config

A possible cause is that the called gcc does not support the armv5 switch. How do I change this?

perhaps you have forgotten to source the settings.sh script.

This script will prepare the environment:

################################################################################
# setup cross compiler toolchain
################################################################################

export CROSS_COMPILE=arm-linux-gnueabihf-

It will also setup Xilinxes Vivado, if it is already installed.

Otherwise follow this instructions for software requirements.

Thanks, yes - that was my problem - i restarted and forgot to run settings.sh.
Now, the Makefile.x86 ran to completion.
