Subject: elf2flt: use CT_ARCH to set target CPU, not CT_TARGET

CT_TARGET is composed as "${CT_ARCH}${CT_ARCH_SUFFIX}", so CT_TARGET may
become something like "armv7", for example. This is used by the configure
script to set the "CPU" variable in the Makefile, leading to a commad line
containing

    -DTARGET_armv7 -DTARGET_CPU="armv7"

In this case the compilation of elf2flt.c fails with "Don't know how to
support your CPU architecture??". Passsing "CPU=${CT_ARCH}" in the make
command line overrides the configured value and solves the problem.
