Hi Marius,

thanks for the review.

So when I rebuilt my entire system a while back with these patches it
was only those few SDL packages that were affected. Unfortunately I have
no way of knowing for sure if it won't happen anywhere else, but it
does seem to be something contained to just SDL(1).

The packages fail with the following error if "mesa" isn't an explicit
input:

ld: cannot find -lGL
collect2: error: ld returned 1 exit status

WDYT? Should I go ahead and push these patches or do you have other
ideas?
