From 08d25f394266eea15c64ed5c583d6af86103166f Mon Sep 17 00:00:00 2001 From: Romain Naour Date: Thu, 20 Jun 2019 12:07:13 +0200 Subject: [PATCH] package/uclibc: backport patch to remove asm constraint on sparc uClibc-ng don't build with gcc 9.1 [1] on sparc due to a new check that "catch illegal asm constraint usage" [2]. This issue has been fixed in upstream uclibc-ng, so we simply backport the fix.
