From ac2aad028daca6ea3aa0c0ccea8d528e896f8349 Mon Sep 17 00:00:00 2001 From: Florin Sarbu Date: Mon, 13 Nov 2017 21:00:11 +0200 Subject: gcc: Use libssp_nonshared linker specs only for ppc/musl Link libssp_nonshared.a only for ppc/musl because glibc already provides the content for libssp_nonshared in libc_nonshared.a and therefore we dont need to make it universal.
