Subject: rules_mk: use gcc versions for external toolchain
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=2555ffb4536e2727465e9a0d426ad3c4f1ef003a;p=openwrt%2Fstaging%2Fstintel.git

rules_mk: use gcc versions for external toolchain

When using the OpenWrt toolchain as an external toolchain the build
failed due to missing LTO support. By choosing the GCC wrappers of
the tools this commit makes sure that the LTO-enabled executables
are being used.
