Two use cases are supported:## 1) Add O= to the make command line# 'make O=/tmp/build all'## 2) Set environement variable BUILD_DIR to point to the desired location# 'export BUILD_DIR=/tmp/build'# 'make'## The second approach can also be used with a MAKEALL script# 'export BUILD_DIR=/tmp/build'# './MAKEALL'## Command line 'O=' setting overrides BUILD_DIR environent variable.## When none of the
