Hi All,

I need to override an append function in bitbake. Just wondering if there
is a way to do it.

do_configure()
do_configure_append()
do_configure_append_mymachine()

I want to replace/override do_configure_append() with
do_configure_append_mymachine(). Is this possible? I do not want to disturb
do_configure and do_configure_append function. All the functions are in the
same bb file.

Thanks,
Vijai Kumar K

_append operations stack up, they can't override eachother, so if MACHINE is 
"mymachine" then the final do_configure that gets executed will consist of 
do_configure, do_configure_append, and do_configure_append_mymachine. You 
should set the contents of those accordingly.

Cheers,
Paul
