From 076fd27da721971f44f681d5a06f68496371d96a Mon Sep 17 00:00:00 2001 From: Thomas Petazzoni Date: Sun, 21 Oct 2018 13:54:13 +0200 Subject: [PATCH] package/gcc: disable libcilkrts when there is no thread support The libcilkrts configure script errors out with "Pthreads are required to build libcilkrts" if the C library doesn't have thread support. To fix that, we disable libcilkrts when thread support is not available. This issue was not noticed until now, because we only regularly build a no-thread toolchain for ARM, and libcilkrts was enabled on ARM only starting in gcc 7.x. This fixes the build of no-thread toolchains on architectures where libcilkrts is supported, i.e x86/x86-64, ARM and Sparc.
