Add and enable remaining 6888x FPU based math override functions. re-use supported versions on '060.
check for x86_64 before i386
Added AROS' own version of variadic/elem.hpp, since the boost's one only treats up to 64 elements.
Added AROS_PP_VARIADIC_SIZE that increases up to 256 arguments boost's own limit of maximum 64 variadic arguments.
Removed trailing commas at the end of parameters list: they're illegal and only worked before because of the too tolerant variadic support macros.
make sure all mutex elements are set in initializers.
revert version change. handle long double in vcformat, and for now print 0x0.0p0 when hex format floats are printed.
update printf doc.
Upgraded boost/preprocessor to the latest version. Converted aros/preprocessor to make use of it. This makes the variadic macros work also when compiling in non-gnu c++ mode.
Added sam440-ppc packages to main build server.
Some tidying following updates to maths functions.
add mathpatch to the build
