[BusyBox] rm -rf confused by directories without "x" bit set.

[Rob Landley]

I ran buildroot as me (not as root), and it created a file that rm -rf won't 
delete.

[landley at dhcppc4 busybox]$ ./busybox rm -rf ../../../buildroot/build_i386
rm: unable to stat 
`../../../buildroot/build_i386/staging_dir/lib/pkgconfig/openssl.pc':

Any suggestions?
