Put something else at the address you want the end of the stack to be at,
e.g. .foo 0x10000 : { __foo = . }
I haven't tried this admittedly.

Or if you want to limit it because you don't want it to hit the top of real
memory, use the MEMORY command to describe the memory of your system
exactly. e.g.

MEMORY
{
    rom : ORIGIN = 0x40000000, LENGTH = 0x80000
    ram : ORIGIN = 0x48000000, LENGTH = 0x200000
}
