build: extend cross compiling check to cover CPPFLAGS (ticket #21)
Use BUILD_CPPFLAGS variable to override CPPFLAGS where necessary in
case of cross compiling, in addition to CC_FOR_BUILD, BUILD_CFLAGS,
and BUILD_LDFLAGS variables introduced earlier to override CC,
CFLAGS, and LDFLAGS, respectively.
* configure.in (BUILD_CPPFLAGS): Define.
* doc/specs/Makefile.am (CPPFLAGS): Define to @BUILD_CPPFLAGS@.
