If one of the perlasm xlate drivers crashes, OpenSSL's build will currently swallow the error and silently truncate the output to however far the driver got. This will hopefully fail to build, but better to check such things. Handle this by checking for errors when closing STDOUT (which is a pipe to the xlate driver). This is the OpenSSL 1.1.1 version of https://github.com/openssl/openssl/pull/10883 and https://github.com/openssl/openssl/pull/10930. Reviewed-by: Mark J. Cox <mark@awe.com> Reviewed-by: Paul Dale David Benjamin <davidben@google.com> (Merged from https://github.com/openssl/openssl/pull/10931)
