From 6880b0150a7c25fd75c5ece80abc49ebf53c38c1 Mon Sep 17 00:00:00 2001 From: Helge Deller Date: Sat, 11 May 2013 19:04:09 +0000 Subject: [PATCH] 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.
