[PATCH] Default Alpha/VMS to DWARF2 debugging only

[Richard Biener]

This changes the default debug format for Alpha/VMS to DWARF2 only,
skipping emission of VMS debug info which is going do be deprecated
for GCC 12 alongside the support for STABS.

It looks like other flavors of VMS never used VMS_DEBUG by default
but only the alpha port did.

I have no good means to test anything here, it might be that we have
alpha-vms specific testcases that rely on the previous default.

OK for trunk?

Thanks,
Richard.
