[Bug 770623] netclock-replay tool breaks cross compile

[GStreamer (GNOME Bugzilla)]

https://bugzilla.gnome.org/show_bug.cgi?id=770623

--- Comment #7 from Alistair Buxton <a.j.buxton at gmail.com> ---
I added the compiler to my path, entered the netclock directory and ran:

strace -s 1000 -f -e execve,file make 2>&1 | grep -E 'execve|gstbase'

and this is the relevant output:

[pid 32295]

-rpath-link)


So the problem here is that it is looking in the sysroot for the libs it just
built, but they aren't in the sysroot because they have not been installed yet.

I also compared the .la files between a cross and a native build and I could
not see any relevant differences there.
