Allow CXX_X86_BINARY to be passed into autogen.sh

This is necessary for building with clang-cl, where $CXX_X86_BINARY needs to
match $CXX (i.e., both invoke clang-cl) so that the compiler switches (which
have been determined based on the nature of $CXX, i.e., are Clang-specific when
$CXX is clang-cl) passed to $CXX_X86_BINARY are actually understood by it.
(Building extensions/source/scanner/twain32shim.cxx failed with "cl : Command
line error D8021 : invalid numeric argument '/Wendif-labels'".)

For now, my local clang-cl build will just pass a suitable CXX_X86_BINARY
similar to the passed CXX (but with --target=i686-pc-windows-msvc -arch:SSE
instead of --target=x86_64-pc-windows-msvc) into autogen.sh.
