Norbert Lange c08fa13d36 package/Makefile.in: use gcc wrappers for binutils tools 
This will use gcc-ar, gcc-nm and gcc-ranlib instead of the normal
binutils tools. The difference is that with the wrappers, gcc plugins
will be automatically picked up.

gcc 4.7 introduced these wrappers, to detect the prefix and keep gcc
specifics out of Makefile.in, a new variable BR2_TOOLCHAIN_BUTILS_PREFIX
will be used to carry the prefix on supported versions.

Note that binutils added some automatic loading with the 'bfd-plugins'
directory (somewhere around 2.28), but the first implementation had
issues, and generally depends on correctly setup symlinks (often broken,
may point to some other gcc's library). The wrappers always work
painless.

The original motivation (now ~2 years in use) was to add "-flto
-ffat-lto-objects" to both BR2_TARGET_OPTIMIZATION and
BR2_TARGET_LDFLAGS, and have target binaries lto optimized.

Not all packages will compile with this option, further work could
white/blacklist packages (adding -fno-lto to the options).
