On ppc32 make tb_set_jmp_target1 behave like it does on a ppc64
Avoids nasty warnings about flush_icache_range from gcc4 and inability to compile [cpu-]exec.c with gcc3 and -O, also the function is much too large to be candidate for inlining anyway. git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@4974 c046a42c-6fe2-441c-8c8c-71466251a162
