(-O1 is fine). This is a new regression introduced in GCC9.
For everyone's safety, extend -O0 hack to dwarf2{expr,loc}.c for
all arm variants with GCC >= 8.

Subject: [PATCH] Preinitialize the sockaddr_un variable to zero
Don't pass random sun_len for the BSD's,
zero the whole structure as recommended for portability.
Reported by Coverity.

* agent.cc (gdb_connect_sync_socket): Preinitialize addr with zeros.
aka "the memcmp bug", from a patch for gcc-10 in
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=95189
Tested on x86_64 by running a full build, install and running it.
Testing that the problem has been fixed with one of the unit tests provided.

Subject: [PATCH] [compiler-rt] [netbsd] Improve the portability of
ThreadSelfTlsTcb
Use __lwp_gettcb_fast() and __lwp_getprivate_fast(), as _lwp_getprivate()
can be a biased pointer and invalid for use in this function on all CPUs.
0's and svr4_exec_displacement read phdrs_target successfully, and we
end up in the rabbit-hole of 0 displacement for pie binaries and then we
can't load our shared libaries from the core file.
