Very good suggestion. That is "my fault" too via the default Debian/Ubuntu setup:

edd at max:~$ grep pipe /etc/R/Makeconf

'--with-readline' '--with-tcltk' '--with-system-bzlib' '--with-system-pcre'
'--with-system-zlib' '--mandir=/usr/share/man' '--infodir=/usr/share/info'
'--datadir=/usr/share/R/share' '--includedir=/usr/share/R/include'
'--with-blas' '--with-lapack' '--enable-R-profiling' '--enable-R-shlib'
'--enable-memory-profiling' '--without-recommended-packages' '--build'

FCFLAGS = -O2 -pipe -g $(LTO)
FFLAGS = -O2 -pipe -g $(LTO)
SAFE_FFLAGS = -O2 -pipe -g -ffloat-store
edd at max:~$
