[PATCH] Remove libsupc++ makefile targets setting -std=gnu++11 or -std=gnu++14


Jakub pointed out that the libsupc++/Makefile has targets with
explicit -std=gnu++11 options, which date from before the default
changed to -std=gnu++14. We no longer need to override the default to
be able to compile the C++11 components. This removes those makefile
targets, as well using pragmas in the sources to avoid
-Wsized-deallocation warnings in the relevant files).

All the files using the default options that used to compile as
-std=gnu++98 or -std=gnu++11 are fine to be compiled as -std=gnu++14
using the default setting.

	* libsupc++/Makefile.am: Remove custom targets for files that need to
	be compiled as C++11 or C++14.
	* libsupc++/Makefile.in: Regenerate.
	* libsupc++/del_ops.cc: Use pragma to disable -Wsized-deallocation
	warnings.
	* libsupc++/del_opvs.cc: Likewise.

Tested powerpc64le-linux, committed to trunk.
