This commit fixes several issues:

- After moving env related code to ./env directory the env_common.o file
is no longer present in the system (has been replaced with built-in.o).

- Use ${OBJCOPY} if available, fallback to system default's objcopy if not
present.

- Extend the script to accept different build directory than current one.
It is extremely handy with OE usage, where source code is separated from
build.

When booting from a non-MMC device, the MMC sub-system may not be
initialized when the environment is first accessed.
We need to make sure that the MMC sub-system is ready in even a non-MMC
boot case.

Therefore, initialize mmc before loading environment from it.

These ARM boards are in nice shape and still being used a lot
with e.g. QEMU, so I can maintain them.

When using omap_hsmmc without the device model then the allocation
of mmc->priv ends up uninitialised.
