Description: Fix ppc64* FTBFS of ghdl's gcc backend
On Power, ghdl fails to build from source with the following error :
/<<BUILDDIR>>/ghdl-0.35+git20180503+dfsg/builddir/gcc/gccbuild/gcc/ghdl -a --GHDL1=/<<BUILDDIR>>/ghdl-0.35+git20180503+dfsg/builddir/gcc/gccbuild/gcc/ghdl1 --std=87 --bootstrap --work=std ../../src/std/textio.v87

It seems that Power specific code rs6000.c has no knowledge of the language_string/lang_hooks.name
which is defined in ortho-lang-7.c:#define LANG_HOOKS_NAME "vhdl"
So adding vhdl in the language type searching. Not sure though if 0 is correct.
