[OpenWrt-Devel] [PATCH] binutils: enable plugin support

[Matthias Schiffer]

--enable-plugin is necessary for gcc-ar, gcc-nm and gcc-ranlib to work, which
must be used with GCC 4.9 for LTO to work.

Without this option, gcc-ar etc. will just fail with

    sorry - this program has been built without plugin support

Using the normal ar from binutils with GCC 4.9 and -flto will cause linking
with static "convenience" libraries to fail.
