From c44cf2cc97df1729577263d2b0cb5263e8cdc4c1 Mon Sep 17 00:00:00 2001 From: Max Filippov Date: Fri, 24 Jul 2015 12:30:31 +0300 Subject: [PATCH] package/gcc: fix libgcc build for xtensa xtensa libgcc can't be built with -mtext-section-literals flag, now coming from TARGET_CFLAGS, because it needs to emit literals to .init/.fini sections, which is not currently supported. Filter -mtext-section-literals flag out of GCC_COMMON_TARGET_CFLAGS.
