Both should work, if you need an cross compiler have a look at ELDK [1]

Wrong file! Please use the source from denx.de, either git from
git://git.denx.de/u-boot.git or a released version from
ftp://ftp.denx.de/pub/u-boot

Thats true for native build (never tested, may not work)

You will need some compiler flags:
 CROSS_COMPILE (prefix for 'gcc' when cross compiling)
 PATH (should contain your toolchain)

I would build it that way:

sheevaplug_config

Well, that is a pre-compiled debian package for armel. The debian
directory contains some information for the debian package system.
