Then you wouldn't even be effected by this patch so the example you gave
does not help. If you don't need to set any special options, then it's
using a cross prefixed pkg-config anyway, or you didn't specify a cross
prefix and it's using the native one. Either way, this patch does not
effect the working pkg-configs.

There is no "possible" way that this is wrong. This is how other
packages work when a cross prefixed pkg-configs. This patch will not

If it went missing? If pkg-config went missing? What are you referring
to missing? How would pkg-config "missing" be effected by this patch?
