parisc: make default cross compiler search more robust (v3)
People/distros vary how they prefix the toolchain name for 64bit builds. Rather than enforce one convention over another, add a for loop which does a search for all the general prefixes. For 64bit builds, we now search for (in order): hppa64-unknown-linux-gnu hppa64-linux-gnu hppa64-linux For 32bit builds, we look for: hppa-unknown-linux-gnu hppa-linux-gnu hppa-linux hppa2.0-unknown-linux-gnu hppa2.0-linux-gnu hppa2.0-linux hppa1.1-unknown-linux-gnu hppa1.1-linux-gnu hppa1.1-linux This patch was initiated by Mike Frysinger, with feedback from Jeroen Roovers, John David Anglin and Helge Deller.
