David Benjamin 32be631ca1 Do not silently truncate files on perlasm errors
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).
