[yocto] i think the explanation of "Build Directory" in dev manual is wrong

[Michael Gloff]

The build dir will definitely be created by the script(s) (assuming
permissions). The default build dir will be created under the level of the
script as 'build', but you can specify any path.

As you point this out I see the sentence:

The TOPDIR<http://www.yoctoproject.org/docs/1.6/ref-manual/ref-manual.html#var-TOPDIR>variable
points to the Build Directory.

can be ambiguous. TOPDIR is not well defined. Maybe it should be called
BUILD_DIR and defined somewhere in local.conf as a default commented out
like DL_DIR and TMPDIR in addition to the ability to specify BUILD_DIR on
the command line.
