Don't allocate a header bellow address 0. With the current code if the script has a PHDRS we always obey and try to allocate a header. This can cause Min - HeaderSize to underflow. It looks like bfd actually prints an error for this case. With this patch we do the same. Found while looking at pr36515. llvm-svn: 326441 2018-03-01 23:25:46 +08:00			`# REQUIRES: x86`
