util/crossgcc/buildgcc: Fix detection of GNAT on recent versions 

gnatgcc is deprecated and in recent GCC releases its purpose is
fulfilled by the gcc binary. In case of a deprecated gnatgcc version is
installed, it doesn't provide the expected output and hostcc_has_gnat1()
fails. In this case, just set the value of CC to gcc.

It's still required to install GNAT in addition to GCC.
