Remove sysv legacy functions

The problem here is the toolchain does not have sysv legacy support and mtd utils is using deprecated bzero and bcopy

Attached patch fixes mtd utils.

Comment 2 Peter Korsgaard 2010-01-17 23:32:12 UTC

Thanks for the patch, but a simpler fix is just to tell mtd-utils to use the bcopy emulation (NEED_BCOPY) like we do for the git version. I've committed a fix doing that earlier tonight (6a772086b7)
