From 152661cde03311b2775db80b5a878c80a2006b6b Mon Sep 17 00:00:00 2001 From: Thomas Petazzoni Date: Fri, 9 Jun 2017 09:49:30 +0200 Subject: [PATCH] gcc: add patch to support musl on SuperH in gcc 5.x Building a toolchain for SuperH/musl works, but the toolchain generate bogus binaries, because the path to the program interpreter is not known (and therefore is /dev/null). This commit backports a patch from gcc 6.x to make SuperH support with musl work properly. The patch is not needed in gcc >= 6.x because the musl support is upstream. The patch is not needed for gcc 4.9 because we had a different musl support patch that had support for all architectures in one patch.
