build: Delete cross-compiling macros.

Now that builtin_compiler is gone, nothing uses these.

-# SYNOPSIS
-#
-#   AX_PROG_CC_FOR_BUILD
-#
-# DESCRIPTION
-#
-#   This macro searches for a C compiler that generates native executables,
-#   that is a C compiler that surely is not a cross-compiler. This can be
-#   useful if you have to generate source code at compile-time like for
-#   example GCC does.
-#
-#   The macro sets the CC_FOR_BUILD and CPP_FOR_BUILD macros to anything
-#   needed to compile or link (CC_FOR_BUILD) and preprocess (CPP_FOR_BUILD).
-#   The value of these variables can be overridden by the user by specifying
-#   a compiler with an environment variable (like you do for standard CC).
-#
-#   It also sets BUILD_EXEEXT and BUILD_OBJEXT to the executable and object
-#   file extensions for the build platform, and GCC_FOR_BUILD to `yes' if
-#   the compiler we found is GCC. All these variables but GCC_FOR_BUILD are
-#   substituted in the Makefile.
