The endianness of the target is currently determined based on
preprocessor symbols. Unfortunately some symbols checked are wrong
(sparc64-linux-gnu-gcc does not define __BIG_ENDIAN__ or SPARC), and
several checks for big-endian architectures are missing.
Fix this by introducing a new preprocessor symbol HAVE_BIG_ENDIAN, which
is set based on meson's knowledge of the target endianness.
Android.common.mk does not need an update, as Android is always
little-endian (https://developer.android.com/ndk/guides/abis.html).
