Trevor Saunders deleted the x86 openbsd 2 & 3 support here.
https://gcc.gnu.org/ml/gcc-patches/2016-06/msg01368.html
With that change, there are now 3 unused files that he missed. I noticed
the gstabs.h file while looking at debugging info related files, and then
did a consistency check and noticed the other two.
Jeff Law preapproved the gstabs.h change, but I still need approval for the
other two files.
OK?
Jim
gcc/
* config/i386/gstabs.h: Delete.
* config/i386/openbsd.h, config/i386/t-openbsd: Likewise.
