Thierry Reding 60e05d7388 build: Fix AX_PROG_{CC,CXX}_FOR_BUILD macros ... Override the cross_compiling and ac_tool_prefix variables by reassigning to them instead of redefining the macros. Redefining them will actually cause the variable names to be replaced instead of their content. Furthermore push the definition of CPPFLAGS before running the checks for the build tools to avoid the host CPPFLAGS from leaking into the build CPPFLAGS. While at it drop the redefinition of AC_TRY_COMPILER which hasn't been used since autoconf 2.50 and make sure that all definitions are properly popped when done (LDFLAGS, ac_cv_prog_CPP, ac_cv_prog_CXXCPP).
