This addresses PR libobjc/78697, allowing a common include dir for all multilib
variants. Tested with a libgc installation in /opt/gcc/include, /opt/gcc/lib32,
/opt/gcc/lib64 and configured with
--prefix=/opt/gcc7 --enable-languages=c,c++,objc --disable-shared
--enable-objc-gc=yes --with-multilib-list=m32,m64 --enable-checking=release
--disable-bootstrap --with-target-bdw-gc-include=/opt/gcc/include
--with-target-bdw-gc-lib=/opt/gcc/lib64,32=/opt/gcc/lib32
Ok for the trunk?
