KICKSTART_LINKBASE and build process

Hi!
This time I've got a generic question about the build process:

I need to change the start address of the bootloader, because Pistachio
shall be loaded from flash memory. I found that the KICKSTART_LINKBASE
is specified twice, in "user/util/config.mk" and
"user/util/configure.in". Is one created by the other? I know, I had to
do an "autoheader; autoconf" thing in the beginning but I didn't check
what they did. Which file is for which process? Maybe someone could just
outline which step takes which input and produces which output?

Yes, one day in future I'll go through all the autoX manuals to
understand the build process used in OpenSource projects. But this far I
got along with just using them ... ;-)

Thanks,

Martin.
