The important one is python_2.7.3.bb.  There's a "largefile"
DISTRO_FEATURE that is sorely under-used and should control whether
the arguments are added.

Tempted to say there should be a largefile.bbclass that you can
control whether it adds to CFLAGS or passes --enable-largefile (as
used by autoconf's AC_SYS_LARGEFILE).  The catch is that you can't
pass the defines globally in every recipe as they change the size of
types, so ABI changes.
