I am running GCC 11.1.0 on hppa64-hp-hpux11.23. 

Using built-in specs.

This only seems to happen when GCC is compiled for the hppa64-hp-hpux11.*
target, not hppa2.0w-hp-hpux11.* or other 32-bit PA-RISC targets. I have tested
this with a much different version of binutils (2.25 vs. 2.37) and have run
into the same issue. Furthermore, I've also tested with GCC 4.7.1 and run into
the same issue.
