svn commit: r364925 - head/sys/sys

[Warner Losh]

New Revision: 364925
URL: https://svnweb.freebsd.org/changeset/base/364925

Log:
  Allow the pseudo-errnos to be returned as well in boot loader
  
  Expose the pseudo-errno values in _STANDALONE is defined so that code
  in the boot loader can make use of them. Nothing uses them today, but
  the zstd support that's coming will need them.
