The options in ${HOST_CC_ARCH}${TOOLCHAIN_OPTIONS} are already passed
via ${CC}/${CXX} and there is no reason to pass them a second time. Thus
we can remove MESON_TOOLCHAIN_ARGS. And when it is removed, the other
MESON_*_ARGS variables revert to the standard CFLAGS, CXXFLAGS and
LDFLAGS, so just use them directly instead.
Apart from the obvious improvement with not passing a lot of options
twice, this also solves a problem where -pie would be passed on the
command line in a way that it would prevent building any dynamic
libraries using meson if using a toolchain that is not built with
--enable-default-pie and if security_flags.inc is used.
