Since SPL needs the of-platdata structures, build these before starting
to build any SPL components.

Sandbox includes this code to provide build coverage. While we retain this
feature we should have sandbox build it. Sandbox does not in fact use the
I2C compatibility mode. Showing a warning for sandbox is just confusing,
since no conversion is expected.

Drop the warning for sandbox.

Sometimes it is useful to build tools with debugging information included so
that line-number information is available when run under gdb. Add a Kconfig
option to support this.

If the final targets depend on both "dtbs" and "dts/dt.dtb",
and -j option is given to the command line, multiple threads
descend into the dts/ directory, which causes build error.

The output reported may be locale-dependent, which results in
unreproducible builds.

  $ LANG=C ld --version | head -n 1
    GNU ld (GNU Binutils for Debian) 2.26

  $ LANG=it_CH.UTF-8 ld --version | head -n 1
    ld di GNU (GNU Binutils for Debian) 2.26

Forcing LC_ALL=C ensures the output is consistant regardless of the
build environment.

Thanks to HW42 for debugging the issue:
