[kdevcustomproject] custom make utitily does not support -j option

[Anatoly Shirokov]

Good day, guys!

I am newcomer. It may be easy question to you, but I still cannot find 
answer. I use custom make utility to build my project. Unfortunately 
this utility does not support -j (job count) option. As a result I get 
error when I try to build the project:

cd '<my project dir>' && custom_make -k -j1
custom_make: unknown switch: j. Stop.
*** Exited with status: 1 ***

Could you please show me the way to make the KDevelop use custom make 
utility without -j option if it is possible.

Thanks in advance.

Anatoly.
