Merge remote-tracking branch 'remotes/quic/tags/pull-hex-20210725' into staging

The Hexagon target was silently failing the SIGSEGV test because
the signal handler was not called.

Patch 1/2 fixes the Hexagon target
Patch 2/2 drops include qemu.h from target/hexagon/op_helper.c

**** Changes in v2 ****
Drop changes to linux-test.c due to intermittent failures on riscv
