[PATCH] hppa64-hpux: Create dummy milli.a archives for binutils and ld testsuites [v2]

[John David Anglin]

In v2, I reworked the change to default.exp in the binutils testsuite to
avoid usings procs from the ld testsuite.

Tested on hppa64-hp-hpux11.11 and x86_64-pc-linux-gnu.  Fixes all fails
due to missing milli.a archive.

Okay?

hppa64-hpux: Create dummy milli.a archives for binutils and ld testsuites [v2]

The hppa64-*-hpux* target has to always link against the milli.a
archive to resolve various millicode routines.  However, this breaks
the binutils and ld testsuites on hosts without the milli.a archive.

This change adds dummy milli.a archives on the hppa64-*-hpux* target
in the binutils and ld testsuites if ld cannot find the file.  The
method used is similar to that for alpha*-*-*vms*.
