cacao: first support of cacao in oe

* for now we only support cacao-cldc
* with cacao-cldc and midapth wie have midp support in oe
* opera-mini and serval other midlets should work now
* installing the packages is not enough
* you have to write shellscripts which looks like
  http://midpath.svn.sourceforge.net/viewvc/midpath/trunk/bin/midpath-test-cacao-cldc.sh?view=markup
* arm is the only support platform for now, others will breakout at not finding
  genoffset.h, which can only generate at the target device with the 
  binary genoffset, upstream is working on diffrent solution, feel free to
  submit genoffset.h for your architecture or machine

++dnl The idea of this solutions comes from bochs-project configure.in
++dnl 
++dnl Add the -lm library if math functions cannot be used without it.
++dnl This check is important on cygwin because of the bizarre way that they
++dnl have organized functions into libraries.  On cygwin, both libc.a and
++dnl libm.a are symbolic links to a single lib libcygwin.a.  This means that
++dnl   1) linking with -lm is not necessary, and
++dnl   2) linking with -lm is dangerous if the order of libraries is wrong
++dnl In particular, if you compile any program with -mno-cygwin and link with
++dnl -lm, it will crash instantly when it is run.  This happens because the
++dnl linker incorrectly links the Cygwin libm.a (==libcygwin.a), which replaces
++dnl the ___main function instead of allowing it to be defined by
++dnl /usr/lib/mingw/libmingw32.a as it should be.
++dnl
++dnl On MacOS X, this test will find that -lm is unnecessary and leave it out.
++dnl
++dnl With uClibc and without libjvm cacao needs to be linked with -lm because of
