[Bug plugins/44459] New: plugin interface depends on name mangling

["amylaar at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

There are a number of global variables that are commonly used for plugins.
By switching the GCC build language to C++, we introduce name mangling,
which means that we loose plugin dynamic link compatibility to previous
versions of gcc.  Also, the interface becomes subject to change when mangling
changes, and will not be compatible if the build compiler uses a different
mangling scheme.  Moreover, it forces to compile plugins with C++.

Global variables that are commonly used for plugins should have C linkage,
and this should be reflected in the plugin header files, so that the
implementation language of the compiler and the plugins becomes decoupled.
