You can configure a UML kernel as any other kernel; UML is seen as an
architecture, and the i386 instruction set (as opposed to x86_64) as a
sub-architecture.

You have to provide make with values for ARCH and SUBARCH at
configuration *and* compilation time.  In practice:

make menuconfig ARCH=um SUBARCH=i386

For example [you can omit -j16, of course]

make -j16 ARCH=um SUBARCH=i386
