2012-12-13build: Fix AX_PROG_{CC,CXX}_FOR_BUILD macrosThierry Reding1-26/+11
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).

2012-11-01build: Don't cross-compile GLSL builtin compilerThierry Reding1-0/+140
The builtin_compiler binary is used during the build process to generate code for the builtin GLSL functions. Since this binary needs to be run on the build host, it must not be cross-compiled. This patch fixes the build system to compile a second version of the source files and the builtin_compiler binary itself for the build system. It does so by defining the CC_FOR_BUILD and CXX_FOR_BUILD variables, which are searched for by the configure script and point to the location of native C and C++ compilers. In order for this to work properly, builtin_function.cpp is removed from BUILT_SOURCES, otherwise the build system would try to generate it before having had a chance to descend into the builtin_compiler subdirectory. With the builtin_compiler and glsl_compiler now being generated at different stages, the build instructions for glsl_compiler can be simplified a bit.
