You have several choices:

  a) system-wide:  $R_HOME/etc/Makeconf    

     (which we provide as a convenience link /etc/R/Makeconf on Debian/Ubuntu)

  b) per-user:     ~/.R/Makevars

     (which is my preferred personal choice to set gcc option, select clang, ...)

  c) per-package   src/Makevars


I like b) a lot to add/remove language-options such as -std=c++0x or -pedantic,
or to select clang / clang++ instead of gcc / g++, ...
