Etienne was (very correctly) alluding to the fact the _creating your own
src/Makefile is strongly discouraged_ as e.g. repeatedly stated by Simon and
others on r-devel or here.  R's ability produce 32 and 64 bit binaries on the
OSs that support it depends criticially on its ability to write its own
Makefile, based on its stubs and the user's Makevars.

Did you by chance mean Makevars here?  Otherwise the trick is fine but for
CRAN I would expect to be met with, ahem, criticism.
