[Buildroot] Question about pkg-config pc files

[Patricia Holden]

I have a TI specific kernel, I got it directly from a TI SDK.   The
comments in ti-sgx-km Config.in says to use ti-sgx, however, there is no
choice in packages for ti-sgx.  I can only choose "ti-sgx-km" or "ti-gfx".
I guess I can pull ti-sgx & create package for it.  Unless someone else has
a better suggestion.
