Building with the experimental support for compositing is broken:

undefined reference to `exp'
That's because it forgets to link with -lm.
However, adding "MATCHBOX_CONF_ENV = -lm" does not solve the issue, as
it still does not link with -lm at all.
Furthermore, the package does not autoreconf, since it is missing the
gconf m4 macros, and Buildroot does not have a package for gconf, hence
we can not even patch Makefile.am and autoreconf.
Patching Makefile.in (in addition to .am) could be a solution, but
support for compositing is explicitly marked as being experimental.
So, just forcibly disable it altogether.

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.
