Christian Marangi a017ae016a spandsp3: fix leaking host header for build tools 
It was discovered that spandsp3 leaks host header on building build
tools.

This was caused by the Makefile not permitting to pass custom header on
compiling build tools. To be more precise it was possible to leak host
header for the tiff library for the tiffio.h header.

Add pending patch to fix this and not depend on the host system header.

Subject: [PATCH 2/2] Propagate CPPFLAGS_FOR_BUILD for build tools
On building build tools, only CC_FOR_BUILD is used with
CPPFLAGS_FOR_BUILD never actually passed. This was probably an oversight
when CPPFLAGS_FOR_BUILD was introduced.
This is especially needed on cross compilation where the header are
placed on a standard location.
To address this case, and make building build tool more robust, actually
pass the CPPFLAGS_FOR_BUILD for each tool.
