Remove elf2aout
Remove the long obsolete elf2aout utility. Should any ports need to know when this left the tree, use 1300077 as the revision so we avoid multiple bumps for the sparc64 removal. Reviewed by: brooks@, emaste@ Differential Revision: https://reviews.freebsd.org/D23527

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.
|
