This patch fixes the kernel entry point address of vmlinux.
The m32r kernel entry address is 0x08002000 (physical).
But, so far, the ENTRY point written in vmlinux.lds.S was not point
the correct kernel entry address.
(before fix)
$ objdump -x vmlinux
vmlinux: file format elf32-m32r-linux
vmlinux
architecture: m32r2, flags 0x00000112:
EXEC_P, HAS_SYMS, D_PAGED
start address 0x88002090 /* NG */

(after fix)
$ objdump -x vmlinux

This fix also remedies the following GDB error message (of gdb-6.4 or after)
at the first operation of kernel debugging:
"Previous frame identical to this frame (corrupt stack?)".
