[Bug fortran/35471] New: gfortran build fails in libgfortran

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

gfortran build fails due to "complex" not being defined in kinds.h.  Though the
system has a <complex.h>, #define for complex is missing in it.  Fix is to
include

#ifndef complex
#define complex __complex__
#endif

at top of kinds.h, or to explicitly check for complex type in
libgfortran/configure.ac
