[LTP] cross compiling errors

[Shane V. <sha...@gm...>]

I'm running an embedded system and do not compile ltp on it instead I
compile it on a host system and then copy it to a SD card (ext3).    There
were a handful of hard coded links in the Makefiles that made this hard.
Below is a patch to address these issues, please review it closely as I'm
not sure if it is the best approach, however it does work.  I also had to
patch the tools/netpipe-2.4/chmod.sh because it was forcing you to be root
but you do not need to be root if your installing into a staging area.  The
modification ignores if your not root if you have CROSS_COMPILE set up.
Regards,
Shane
