if you're not using arm, or you're using softfp, then feel free to stop 
reading

i've backported the patches from upstream gcc/glibc to use the new ldso paths 
for arm hardfp targets.  atm, this is in glibc-2.15 and gcc-4.5.3 and 
gcc-4.6.3.  so if you have one of these systems where you're running softfp by 
default, you might want to be careful when you update glibc as the ldso will 
change and all your dynamically linked ELFs will probably go kablooie :).

if this happens to you, you can easily recover.  launch the static rescue 
shell:
	/bin/bb
then symlink the old path to the new one:
	ln -s ld-linux-armhf.so.3 /lib/ld-linux.so.3

this is to support the cross-distro standardization of armv7/hardfp work.
