The BUILD_EXEEXT and BUILD_OBJEXT variables in AX_PROG_CC_FOR_BUILD are broken
again in Autoconf 2.70 and later.

It seems to be caused by an internal change of AC_SUBST macro that prevented
the "variable name" argument in AC_SUBST to be macro-expanded.

I took the time and found the right way to make variables work. (Patch 1)

There have been a variable rename workaround for "ac_cv_c_compiler_gnu" in
this AX_PROG_CC_FOR_BUILD module, as the code is similar, I modified the
"ac_cv_c_compiler_gnu" code as well (Patch 2), so that the code alignes with
the BUILD_EXEEXT and BUILD_OBJEXT solutions.
