@majorheading 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.
