  Dear GMP devs,

  As I reported the same issue to gentoo bugzilla and retried to reproduce
  for them with all logs attached,
  I've found out that iproute2 magically started to compile OK.

  However, there were other sources whose compilation was broken.

Unfortunately, I don't have time to isolate this problem.

I long shot would be to disable assembly in the GMP build (by means of
.../configure --disable-assembly).  The arm64 asm in GMP 6.2.1 followed
the ABI docs of the time, which turned out to cause problems at least in
some environments.
