[alsa-devel] [PATCH - use build platform compiler while cross compilation 1/1] use build compilers in cross compilation setup

This patch is to make the build script always use the build platform
compilers, especially during the cross compilation process, since the
Makefile will pick up the cross compilers instead of the compilers on
the build machine.

+# 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.
