tools/env: cross-compile fw_printenv without setting HOSTCC
fw_printenv is a program which mostly runs on the target Linux.
Before switching to Kbuild, we needed to set HOSTCC at the
command line like this:
make HOSTCC=<your CC cross-compiler> env
Going forward we can cross compile it by specifying CROSS_COMPILE:
make CROSS_COMPILE=<your cross-compiler prefix> env
This looks more natural.
