Unfortunately we have some experience with these replacement recipes and
they need some "special" handling. You need to install make into a
subdirectory off ${bindir} and then add it to PATH in the webkit recipe.
There is precedent for this:

http://git.yoctoproject.org/cgit.cgi/poky/commit/?id=3f05622bac998f351168eb49a5ca96e7473f51be

So BBCLASSEXTEND the make recipe, add a PROVIDES, then do a
EXTRANATIVEPATH += "make-native" in the webkit recipe.

The reason for this elaborate dance is so we avoid races, nothing should
be executing the make binary when we do anything to it with sstate
(install or remove it). Admittedly this is much more critical when there
is an associated library like bzip but we need to set the right example.

Cheers,

Richard
