util/crossgcc: Document how to build the toolchain for another location

One common issue with the toolchain is that it takes a very long time
to build while it's somewhat volatile inside the coreboot tree.

Installing the toolchain elsewhere helps keep it safe but since there
is no reliable default location outside the tree, keep the default
as is.
