Subject: [PATCH]   Modify sdksyms.sh to receive $top_srcdir as first argument.

  If the basename of header file processed by cpp matches $top_srcdir,
check for extern symbols in the output, and add to the xorg_symbols
vector.
  Possibly a better solution then using this script would be to somehow
tell the linker to not drop any symbols from the binary being generated.
