libc: fix typo in comments: NO_SRSC -> NO_SRCS

Add ACL support for FFS. From FreeBSD.

Restrict -fno-sanitize=function to Clang/LLVM only

The base GCC version 6,x does not support this option.

Disable sanitization of -fsanitize=function in libc

Generated code for the checks (in at least libunwind) depends on the C++
runtime feature of RTTI.

Pass -fno-sanitize=function to LIBCSANITIZERFLA

Drop the USE_LIBTRE build option

libtre cannot be used any more as a replacement for regex(3).
Tt does not build and the library development is stalled in upstream.

Add hooks for RUMPRUN build of libc

If "yes", does the following (default "no"):
* prevents ASM syscalls from being built (librump provides syscalls)
* does not include compat (useless when application is linked with libc)
* does not build tags (no /var/db to install them to)
* does not include tls

==> libc for rumprun can now be built against unmodified NetBSD sources

MKCOMPAT fixes for when compat MACHINE_CPU != normal MACHINE_CPU

Introduce GENASSYM_CPPFLAGS for options during genassym processing.
Consistently drop assembler flags.

Include compiler-rt in libc, libm and libkern.

If MKREPRO=yes, make the tags file refer to /usr/src
instead of referring to the actual source directory ${NETBSDSRC}.

Use a separate variable for the use of GCC's unwind code.

Use the quad support from compiler-rt for MKLIBGCC=no.

Rename USE_LIBGCC to HAVE_LIBGCC and retry using it as flag on unwind.h.

Include compiler-rt and libunwind in libc for Clang/x86 builds.

Don't pass assembler flags to cpp for genassym.

Match against LIBC_MACHINE_ARCH for MKCOMPAT

Just build the legacy stuff for earm (for now).

for earm, make sure to build getdirentries man page

Add CPPFLAGS+= -I${NETBSDSRCDIR}/sys for earm compat

for EARM, just build __lwp_park50 compat for libpthread until the situation
is involved.

Fix inverted test.

Since earm is new, don't bother building the compat libc code since there
is nothing that can use it.

Rename BUILDCOLD to BUILD_LEGACY and provide a preprocessor macro that
can be used in code files that aren't easy to split up. Add the removal
to the major bump todo list.
