As noted in NEWS, strace now enforces mpers support by default (in order
to make aware of the possibilty of incorrect non-native personality
decoding early); looks like your compiler doesn't support producing
binaries for the compat personality.  You can either try to use another
compiler or provide --disable-mpers to the configure script.

As GCC for AArch64 doesn't support generating ARM EABI binaries at all,
this issue will probably be somehow tackled in the future.
