Ticket #52705: config.log

This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.

It was created by libpng configure 1.6.26, which was
generated by GNU Autoconf 2.69.  Invocation command line was

  $ ./configure --prefix=/opt/local --disable-dependency-tracking
