 I can see:

hppa64-hp-hpux11.23  -FAIL: objcopy executable (pr25662)
hppa64-hp-hpux11.23  +FAIL: ld-elf/pr30791b
hppa64-hp-hpux11.23  +FAIL: relocatable with script

compared to commit 77cb5ee0f268 ("gas: pru: Add flag to select core 
revision") after which linking `milli.a' was added; I hope it's expected.

 Hmm, I think it would be safer long-term (even if nothing breaks right 
away) if our dummy `milli.a' library lived on its own in a separate 
directory such as `tmpdir/milli' that isn't expected to be ever used by 
any tests, in particular generic ones.  This way adding " -Ltmpdir/milli" 
won't interfere with tests that want or don't want to have `tmpdir' in the 
library search path for some reason.

 I can see `alpha*-*-*vms*' already uses " -Ltmpdir", so we have previous 
art, but I'd rather fix it (separately, definitely an expectation for you 
to do it) than add another case.

 Why is this addition required for `hppa*64-*-hpux*' while not for 
`alpha*-*-*vms*'?
