No one tests yacc/byacc. Let's just request bison specifically.

configure.ac sets up a PYTHON2 variable, which is what we want
AX_PYTHON_MODULE to use (since we only use Python 2 for now).
NOTE: This is a candidate for the 9.0 branch.

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).

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.
