[Buildroot] SDL2_ttf requires libpng12 but Buildroot installs libpng16

[Peter Thompson]

Hi Thomas,
The  answer is that I was unaware of the Buildroot autotools capability.
Without really searching, I assumed if something was not already in
Buildroot, I had to add it manually.    I have re-examined the Buildroot
users manual
     https://*buildroot*.org/manual.html
and the Free Electrons notes
     http://free-electrons.com/~thomas/buildroot/manual/html/ch11.html
and it seems like a much better way to do it and is something within my
capability.

Having said that,  I learned a lot doing things manually even though it was
extremely frustrating and took me a very long time.    I almost gave up a
couple of times.    The help I got from you guys was super - and really
encouraging.

Thanks
Peter
