dlsym(RTLD_NEXT, func_name). This fails for pthread_join() as it
is present both as a stub in libc and as real operation in libpthread
and the search order is "libtsan.so libc.so libpthread.so".
Force the order "libtsan.so libpthread.so libc.so" so symbols
get intercepted from libpthread first.

HOST_CPPFLAGS, HOST_CXXFLAGS, but not LIBRARY_PATH because it breaks
the build. These variables are necessary to support building NetBSD
from a GNU Guix or NixOS host, where /usr/include, /lib, and all
but /bin/sh do not exist. In many cases, support for HOST_CPPFLAGS
was incomplete. From Ryan Sundberg
no idea why it was enabled as we can't easily target 32 bit.
if we figure this out for aarch32, the subdir names etc will
probably be different, or we can just revive the deleted

a regression in sh. In addition to the intended change (based on the
commit message), an apparently unintended change was made, inverting a
comparison. This broke sh builds and our workaround (so far) was to
compile xlint/lint1 with -O0.
Revert the comparison to what it was before and remove the -O0 hack
from xlint/lint1.

Include order of bpapi.h and netbsd-elf.h was swapped when official
support for arm*--netbsdelf-eabi{,hf} was added to GCC10. This seems to
cause critical inconsistencies, which results in SIGSEGV for as(1) on
earmv6hf{,eb} and some other regressions for many arm variants.
With this fix, everything work just fine as far as I can see.
Thanks skrll and mrg for discussion!
Fix tests/usr.bin/gdb/t_regress:pie on aarch64eb (types of auxv was
misinterpreted), and hopefully other strange behaviors on aarch64{,eb}.
This is a regression introduced in GDB11. Neither gdb.old nor release
branches are affected.
Get rid of -O0 hack for GDB for hard-float arm. This was necessary because
libunwind did not support s0-s31. Note that for *most* cases (not all!),
-O0 stops using VFP registers for general purposes.
Also note that this hack was incomplete. We had to compile every functions
with -O0, that can be unwinded. Otherwise, GDB crashed every time exceptions
were raised.
Assembler codes generated by GCC are identical with that of our local
fix in rev 1.26 for 32-bit processors, and no significant changes for
64-bit processors also.

rs6000: Fix cpu selection w/ isel (PR100108)
There are various non-IBM CPUs with isel as well, so it is easiest if we
just don't consider that flag here (it is not needed).

remove unused ARM_EABI_UNWIND_TABLES and __UNWIND_TABLES__.
clang defines __UNWIND_TABLES__, but doing this in GCC triggers the
need for more libgcc / libc unwind functionality to be added, and this
code has never been enabled for netbsd/earm. (could potentially clean
up unused code in libc now, or, revive this once the full support has
been implemented..)
