I'm using CentOS. But the problem was "make localmodconfig" is not
working. I don't see how a question related to "building kernel.org
kernel" relates to distribution, just because the problem was
discussed in a distribution's forum. Same kind of discussion can be
found(about faulty behaviour of "make localmodconfig") in
debian/ubuntu forums if use try google.

Not understanding how this relates to ignorance of "make". may be you
are pointing about the environment variables and stuffs.

I'm trying to tune up my kernel build. so i need to see which way it
performs the best. During development i dont "clean". I dont even make
the whole tree. i just build the part of the tree i'm developing.

Yep, i have run make menuconfig to see what's enabled. But you there
is thousands of options, its not practical to go through all of them.
I just see common options. Like if the driver for my ethernet card is
enabled "only". stuffs like that.

I managed to make it through without "perl" till now.

Honestly i've never checked it. i've just checked. nothing comes up
with --help, -h -?. All are unknown options.

English is not my native language. When i type quickly sometimes,
correcting all the spelling mistake seems like a burden. Sorry for the
annoyance in caused.
