[OE-core] [RFC][PATCH] u-boot-mkimage: allow building target version of the tool

[Denys Dmytriyenko]

From: Denys Dmytriyenko <denys at ti.com>

u-boot doesn't really support building its tools for the target, as they are
built with HOSTCC compiler, which is also used to compile fixdep utility
that gets executed during the build. Since it might be beneficial to have a
target version of mkimage, let's hack it to build fixdep in a separate step.
