make -j 4 command in ubuntu

everything got build properly but at last it showed error as

collect2: ld terminated with signal 9 [Killed]

You should use make -j with a number lower than 4, it looks like you ran out of memory when linking.

What I did for x86_64 bit system was
set hostas x86_64,
disable assert
and enable optimsed, (For All these config options was collected after going through ./configure --help)
and then simply make
followed by make install

I did the following which might not the best I am not clang developer yet.

./configure --enable-optimized --disable-assertions --enable-targets=x86_64
