Ed, All,

On 2019-03-22 16:59 +0000, Ed Blake spake thusly:

With your series, there is no user of libgomp in Buildroot, so I
suppose this is for your own local packages, right?

Actually, if we have packages in Buildroot that may use OpenMP, then it
is only optional for them, then. Do you know of such a package? The goal
being to actually add a runtime-test that gomp works.
