Hello!

>>> When you are configuring crosstool-ng, under "C-library" menu, there
>>> is an option "Force unwind support" which you need to enable.

Thanks a lot for help provided! I was able mo move a little bit
further but unfortunately got another error:

[INFO ]  =================================================================
[INFO ]  Installing C library headers & start files
[ERROR]    make[2]: *** [/usr/include/limits.h] Error 1

more info on this error.

build.log at the end contains the following:

Seems like 'install_root' parameter isn't passed to the sub-make
process and that's why install procedure tries to perform action from
FS root.

Do you have any ideas why this happens?
Please take a look in the attachment for detail logs and configuration I using.

Thank you!
