Hi, thank you for your work.

I'm having this problem after configuring and running make, and nobody talk
about it in forums, stackoverflow, ....

btw I'm using Fedora 23
* Attached .config file

Could you say me what am I doing wrong?
Thank you in advance

Thanks for the report. Could you:

*) Disable ccache support

*) Use uClibc-ng instead of uClibc snapshot, since we actually test
uClibc-ng support, but not uClibc snapshot support

*) Make sure you don't have anything weird in your PATH.

(Those are just basic sanity checks since I don't know specifically
where this error is coming from).

Best regards,

Thomas

This is _extremely_ strange. There is no reason at all why the system's g++
should call the cross-as...

Do you have something particular in your environment?
