From 11ec38b6950cf3337b52fb97f27c2fd7c776c5c2 Mon Sep 17 00:00:00 2001 From: Thomas Petazzoni Date: Tue, 8 Oct 2013 20:17:15 +0200 Subject: [PATCH] toolchain-external: fix Linaro ARM toolchain support This commit fixes bug #6452 (eglibc from Linaro 2013.07 not copied to target correctly) by: * Copying only the relevant library loader to the target on ARMhf (i.e ld-linux-armhf.so and not ld.so*). This is needed since Linaro toolchains provide two library loaders, one ARMv7 hf, and one ARMv4 soft-float. * Making sure a $(TARGET_DIR)/lib/arm-linux-gnueabihf/ symbolic link to $(TARGET_DIR)/lib/ exists, since the dynamic loader of Linaro toolchains expects libraries to be found in $(TARGET_DIR)/lib/arm-linux-gnueabihf/.
