Peter Korsgaard 0e99bef2fb package/Makefile.in: export O= to post-build/image scripts for out-of-tree builds
Sometimes it can be interesting to call back into buildroot from a
post-build/image script (E.G. make printvars or similar). For this to work
correctly with out-of-tree builds we need to pass O= to make, but this is
currently not available in the environment of post-build/image scripts.

In concept, O could be derrived from BUILD_DIR (E.G. by stripping /build),
but directly exporting O is cleaner.

O= cannot be exported globally as it interferes with various build systems,
so instead add it to EXTRA_ENV.

README

Buildroot is a simple, efficient and easy-to-use tool to generate embedded
Linux systems through cross-compilation.

The documentation can be found in docs/manual. You can generate a text
document with 'make manual-text' and read output/docs/manual/manual.text.
Online documentation can be found at http://buildroot.org/docs.html

To build and use the buildroot stuff, do the following:

1) run 'make menuconfig'
2) select the target architecture and the packages you wish to compile
3) run 'make'
4) wait while it compiles
5) find the kernel, bootloader, root filesystem, etc. in output/images

You do not need to be root to build or run buildroot.  Have fun!

Buildroot comes with a basic configuration for a number of boards. Run
'make list-defconfigs' to view the list of provided configurations.

Please feed suggestions, bug reports, insults, and bribes back to the
buildroot mailing list: buildroot@buildroot.org
You can also find us on #buildroot on Freenode IRC.
