usb_updater: allow to define target environment
It is necessary to be able to build usb_updater for both host and
board environments.
When building for board environments the appropriate compiler and
binutils are defined in the environment. Allow the environment
definitions to take precedence over local definitions.
BUG=none
TEST=inside and outside chroot:
. ran 'make clean; make; verified that command can be run on the
host.
inside chroot:
. ran 'emerge-kevin ec-utils' and verified using the 'file' utility
that the executable in /build/kevin/usr/sbin/usb_updater is built
for arm
