You have to set the crosscompiler in menuconfig as well as the PREFIX.

Set CROSS in "Build Options" and PREFIX in "Installation Options"
The default PREFIX is:
$ grep ^PREFIX .config
PREFIX="./_install"

Hm. Issuing "make install" works for me here..
I bet that the path for PREFIX in your .config doesn't exists, yes?
