caused a segfault. It turns out that in pre-7.0 systems if you do
getenv("amd_enable=YES") it will return the setting of the environment
variable "amd_enable" but now it returns NULL. I think I found the
places where sysinstall was potentially relying on that old behavior.
Fix is to make a copy of the string to be used for the getenv(3) call,
look for a '=' character in it, and replace it with '\0' if one is
found. Stuck to sysinstall's typical coding standards despite urges
to do otherwise.
