First, I think you mean -fobjc-gc. Second, I'm not sure why you think  
it's needed, because R doesn't use any Obj-C itself so it won't have  
any effect on the R library at all. Only your application needs to use  
it if it wishes to use the gc. Finally, you can always add flags via  
the usual environment variables for example OBJCFLAGS (see B.3 in R- 
admin and ./configure --help).
