Subject: We use different toolchain directories for different ARM archs, so we should set... 
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=a3989e3dbd80248789ee379538e6de22c1d47d0e;p=openwrt%2Fstaging%2Faparcar.git

We use different toolchain directories for different ARM archs, so we should set the default arch of gcc to reflect this.

This enables EABI support for armv4 CPUs.
