This utilizes the qemu-user system used by gnutls. This also
deprecates the previous aarch64 build.

This allows testing whether exported symbols are sufficient for the
included test suite.

This adds all exported symbols in the map files explicitly under
the following rules:
 - Symbols mentioned in internal headers go in a section which is
   valid only for testing, and linking with these symbols will break
   in library updates.
 - Symbols mentioned in installed headers go in the exported sections
   and are considered part of the ABI.
 - All internal symbols move to internal headers.
 - The _nettle_md5_compress and _nettle_sha1_compress become exported
   without the _nettle prefix, due to existing usage.

* aclocal.m4 (NETTLE_CHECK_IFUNC): fix quoting so that
  AC_LINK_IFELSE/AC_TRY_LINK is defined outside of this test.

These are produced by Apple's Xcode 10 compiler.

Extend arm/README to provide some background on considerations to be taken into
account when writing assembly routines supposed to work in big and little memory
endianness.

Adjust sha1-compress, sha256-compress, umac-nh, chacha-core-internal,
salsa20-core-internal and memxor for arm to work in big-endian mode.

Introduce m4 macros to conditionally handle differences of little- and
big-endian arm in assembler code.
