btcdrak commented at 3:57 AM on March 26, 2016:

Not sure I agree with -j10 as a default for documentation. Better leave it out entirely as is the case for existing documentation.

accraze commented at 4:27 PM on March 26, 2016:

yeah @btcdrak I can understand that .... do you also think I should get rid of -j10 on line 270 as well?

btcdrak commented at 4:30 PM on March 26, 2016:

@accraze Yes. Advanced users will add their own -j settings as appropriate.

Not sure why there is an scp line here, seems othogonal.

you're right, it should be removed :+1:

Could remove this and then also squash the commits, please?

-unknown appears to be incorrect also.

You are installing the ARM specific toolchain before actually telling the reader that you'll be building for ARM.

petertodd commented at 12:42 PM on March 30, 2016:

Just change the header of this section to "ARM Cross-compilation"
