Merge the ./config directory between GCC and Binutils
This pulls in the missing Binutils pieces into the ./config
directory. Contains these missing Binutils changes:
2014-08-14 Alan Modra <amodra@gmail.com>
* plugins.m4: Test for dlfcn.h or windows.h here to set default
for --enable-plugins. Report error if someone tries to enable
plugins on a host we don't support.
2014-08-19 Alan Modra <amodra@gmail.com>
* plugins.m4 (AC_PLUGINS): If plugins are enabled, add -ldl to
LIBS via AC_SEARCH_LIBS.
