Do you happen to have a newer version of this patch somewhere?  I tried
applying this against a qemu CVS snapshot made today and qemu-arm just
seems to go into an infinite loop.

I think there's but one or two issues preventing a 'native' ARM glibc
build under qemu.  Something in my 'make' binary is driving qemu-arm
crazy, because I consistently get this (without your v5 patch):

[...]

              Trying pattern rule with stem `config'.
              Trying rule prerequisite `scripts/gen-as-const.awk'.
              Trying implicit prerequisite `config.sym'.
              Looking for a rule with intermediate file `config.sym'.
qemu: uncaught target signal 11 (Segmentation fault) - exiting
sh-2.05b# 

(I did apply the patch.qemu_selfmodify patch you posted a while ago.)
