    tests: sanitize build of test cases.

    Fix compiler paths when searching for dependencies, especially when they
    are in non-standard locations. Drop _DEPENDENCIES that are automatically
    generated. Also include a few cosmetics (vertical alignment).

Hi, Gwenole

Your recent commits in libva staging branch result in DSO regression issue.

make[3]: Entering directory `/home/cc/libva/test/encode'
  CCLD   h264encode
/usr/bin/ld: h264encode_x11.o: undefined reference to symbol 'XOpenDisplay'
/usr/bin/ld: note: 'XOpenDisplay' is defined in DSO /opt/X11R7/lib/libX11.so.6 so try adding it to the linker command line
/opt/X11R7/lib/libX11.so.6: could not read symbols: Invalid operation
collect2: ld returned 1 exit status
make[3]: *** [h264encode] Error 1

Could you take a look and fix it ?

Thanks
Haihao
