ncurses 6.2 - patch 20200808

+ improve discussion of the system's tic utility when used as part
  of cross-compiling (discussion with Keith Marshall).
+ modify configuration checks for build-time tic/infocmp to use
  AC_CHECK_TOOL. That can still be overridden by --with-tic-path and
  --with-infocmp-path when fallbacks are used, but even if not using
  fallbacks, the improved check may help with cross-compiling
  (discussion with Keith Marshall).
+ other build-fixes for Ada95 with MinGW.
+ modify Ada95 source-generation utility to write to a file given as
  parameter rather than to the standard output, allowing builds with
  MinGW.
