avoid multiple bumps for the sparc64 removal.

-.Sh NAME
-.Nm elf2aout
-.Nd "Convert ELF binary to a.out format"
-.Sh SYNOPSIS
-.Nm
-.Op Fl o Ar outfile
-.Ar infile
-.Sh DESCRIPTION
-The
-.Nm
-utility is used to convert an ELF formatted binary,
-namely a kernel, to an a.out formatted one.
-Most
-.Tn OpenBoot
-firmware require an a.out format or FCode boot image
-and this utility is designed to accommodate.
-If
-.Ar infile
-is not in ELF format, an error message will be presented.
-.Sh DEPRECATION NOTICE
-The
-.Nm
-utility is not present in
-.Fx 13.0
-and later.
-.Sh SEE ALSO
-.Xr elf 3 ,
-.Xr a.out 5
-.Sh HISTORY
-The
-.Nm
-utility first appeared in
-.Fx 4.6 .
-.Sh AUTHORS
-.An -nosplit
-The
-.Nm
-utility was written by
-.An Jake Burkholder Aq Mt jake@FreeBSD.org .
