Some bootloaders (e.g. VxWorks 5.5 System Boot) on TX49 systems do not
support loading 64-bit kernel images.  Work around this by selecting
BOOT_ELF32, to support running both 32-bit ("vmlinux" with
CONFIG_32BIT=y) and 64-bit ("vmlinux.32" with CONFIG_64BIT=y) Linux
kernels on TX49 devices with such a boot loader.

Tested on RBTX4927, running a Debian jessie 32-bit mipsel nfsroot userland, and
some 32-bit and 64-bit test binaries.

Crap can work. Given enough thrust pigs will fly, but it's not necessarily a
good idea.                                                [ RFC1925, 2.3 ]
