write_buildcustomize.pl no longer writes to STDOUT
write_buildcustomize.pl now opens lib/buildcustomize.pl itself, instead of
writing to STDOUT and relying on the Makefile to set up redirection. This
means that an empty lib/buildcustomize.pl is not created if
write_buildcustomize.pl fails to compile (for whatever reason), and permits
write_buildcustomize.pl to delete (or attempt to delete) the output file if
it detects an error.
Hard code the output file name (lib/buildcustomize.pl), as it's the same on
all platforms, and @ARGV is already used to optionally pass a directory for
write_buildcustomize.pl to change to before running.
Experimentation suggests that various make utilities don't delete a file
created by redirection even if an error occurs. Hence this should be more
robust.
Add -f to the miniperl commandline when running write_buildcustomize.pl to
avoid reading in any existing lib/buildcustomize.pl. write_buildcustomize.pl
doesn't need the setup provided by lib/buildcustomize.pl, and running it
might cause errors which prevents writing out a correct version, making an
incomplete build harder to recover from.
