Do you mean the R-admin manual?  Your 'updates' all seem to be 
failures to follow that manual.

Assumed by whom?  Not by our manual.

Why do you do this rather than use R's included gettext?

No, please don't: rather RTFM.  The R-admin manual has things like

CC="gcc -m64"

and it seems you needed

CC="cc -m64 -xarch=native"

If you need specific options to run a compiler, they are part of CC 
(and so on) and not CFLAGS.
