place for the output files (including .config).
Example:

kernel source code: /usr/src/linux-3.X
build directory: /home/name/build/kernel
To configure and build the kernel, use:
- cd /usr/src/linux-3.X
- make O=/home/name/build/kernel menuconfig
- make O=/home/name/build/kernel
- sudo make O=/home/name/build/kernel modules_install install

"make silentoldconfig"

"make defconfig" Create a ./.config file by using the default

"make ${PLATFORM}_defconfig"
- Create a ./.config file by using the default

NOTES on "make config":
+
- having unnecessary drivers will make the kernel bigger, and can
under some circumstances lead to problems: probing for a
nonexistent controller card may confuse your other controllers
+
- compiling the kernel with "Processor type" set higher than 386
will result in a kernel that does NOT work on a 386. The
kernel will detect this on bootup, and give up.
+
- A kernel with math-emulation compiled in will still use the
coprocessor if one is present: the math emulation will just
never get used in that case. The kernel will be slightly larger,
but will work on different machines regardless of whether they
have a math coprocessor or not.
+
- the "kernel hacking" configuration details usually result in a
bigger or slower kernel (or both), and can even make the kernel
less stable by configuring some routines to actively try to
