[PATCH v2 1/2] build: Preserve *_FOR_BUILD environment variables in all cases.

Browse Source 
They were preserved in the `"${build}" != "${host}"` case, but not in the
`"${build}" = "${host}"` case.

Each of the following commands produces the same build directory with and
without the patch:

./configure --build=x86_64-make_autoconf_enable_cross_compiling-linux-gnu --host=x86_64-linux-gnu
CC_FOR_BUILD=/tmp/gcc_for_build ./configure --build=x86_64-make_autoconf_enable_cross_compiling-linux-gnu --host=x86_64-linux-gnu
./configure

The following command produces a Makefile containing `CC_FOR_BUILD = $(CC)`
without the patch and containing `CC_FOR_BUILD = /tmp/gcc_for_build` with the
patch:

CC_FOR_BUILD=/tmp/gcc_for_build ./configure

ChangeLog:

	* configure.ac: Preserve *_FOR_BUILD environment variables in all cases.
	* configure: Regenerate.
