I suspect these stem from R's own configuration, set at its compile time.
Try this:
edd@max:~$ R CMD config CPPFLAGS
edd@max:~$ R CMD config CXXFLAGS
-g -O3 -Wall -pipe -Wno-unused -pedantic
edd@max:~$ R CMD config CXXPICFLAGS
-fpic
edd@max:~$
See 'R CMD CONFIG --help' for more, and the $RHOME/etc/Makeconf file for the
settings.
