[Rd] PATCH to Makefile.in w/ Makeconf LIBR variable update to allow builds within R to find Framework

[Cyrus Harmon]

Dear r-devel,

When R has been installed in a non-standard location (or any location  
where Apple's version of gcc isn't going to, by default, look for  
frameworks specified with the -framework arg), builds of R packages  
fail because the linker can't find the framework. The following patch  
to Makefile.in enables Makefile to patch Makeconf appropriately to  
drop in the -F argument to the appropriate place.

Thanks for considering this,

Cyrus
