rpm: Add workaround for debugedit-segv
[ YOCTO #4089 ]
On PPC and MIPS, there appears to be a condition that causes
debugedit to segfault. The segfault is related to a call into
the md5hash algorithm, an address of '0', and a size > 0 is passed
causing the access of the address to segv.
This workaround may prove to be the final fix, but it's currently
unclear what the actual cause of the 0 address is.
