[PATCH] gst-ffmpeg: Fix build failures from sstate relocation

[Richard Purdie]

This is a similar situation to:
http://git.yoctoproject.org/cgit.cgi/poky/commit/?id=3c96a5386355969428163ddb60216cc989e00b3d
    
Builds were failing with a failure in configure:

collect2: ld returned 1 exit status
    
The reason being the --sysroot option is missing from the gcc commandline and
its looking in nightly-x86, not nightly-world in this case.
    
There is no reason to add extra -L options to the compiler, the sysroot already
takes care of this. We can therefore simply remove this incorrect CC line.
