This is enabled by default in the main configure.sh, but apparently is supposed to be disabled if the hardware doesn't support it. Unaligned reads is only supported on armv6 and newer. Change-Id: Ie1412e36a14036bbb4fe7b89aa36a178f35b2228

Object files are built at the place where configure is launched.

All boolean options can be negated. The default value is the opposite

of that shown above. If the option --disable-foo is listed, then

the default value for foo is enabled.
