added INCOMPATIBLE_MACHINE
we have COMPATIBLE_MACHINE but that does not allow to say that
a package is supported by all except a certain machine.
a regexp like "(?!arch)"
This mechanism can be used to exclude certain machines.
Idea is that in binutils and gcc you can use this to specify that
a certain version does not support a certain machine
