[PPC, committed] Fix bootstrap for non-SVR4 targets.

[PPC, committed] Fix bootstrap for non-SVR4 targets.

[Iain Sandoe]

The recent change to move code into the new rs6000-call.c file is missing a
default value for the TARGET_NO_PROTOTYPE value (which only affects targets
that don’t include svr4.h).  Fixed by moving the fallback setting from
rs6000.c (which has no uses now) to rs6000-call.c.

pre-approved on IRC by Segher,

tested on powerpc-ibm-aix7.2, powerpc-darwin9,
applied to mainline,
