Fix handling of non-contiguous argv + envp in setproctitle()
The two arrays might not reference contiguous memory, and assuming they
are does break at least now on GNU/Hurd, which contains an unmapped
memory block between the memory used by the two arrays.
Just check that each element is strictly after the previous one, so that
we know there are no unmapped memory blocks inbetween.

Fix ELF definitions for MIPS in local-elf.h
Add a check for _MIPS_SIM inside the __mips__ #elif to detect mips64el
and use ELFCLASS64 in that case. Note that we can't use defined(__mips64)
here because that is also defined when the n32 ABI is in use, which uses
ELFCLASS32.

Fix broken mmap() usage in nlist() by switching to pread()
The offset is not page aligned, which makes mmap() return EINVAL on
Linux. Switch to use pread() which handles unaligned offset and non-page
sized reads, and because we are already loading parts of the executable
by read() calls, so there's not much point in using mmap() anyway.

Fix heap buffer overflow in fgetwln()
In the function fgetwln() there's a 4 byte heap overflow.
There is a while loop that has this check to see whether there's still
enough space in the buffer:
if (!fb->len || wused > fb->len) {
If this is true more memory gets allocated. However this test won't be
true if wused == fb->len, but at that point wused already points out
of the buffer. Some lines later there's a write to the buffer:
fb->wbuf[wused++] = wc;
This bug was found with the help of address sanitizer.

(such as GNU-based systems or NetBSD) will fail to build. In which case,
as the code has to be modified anyway, we might just as well use the
correct declaration.

Move setproctitle() automatic initialization to its own library
The automatic initialization cannot be part of the main shared library,
because there is no thread-safe way to change the environ global
variable. This is not a problem if the initializaion happens just at
program load time, but becomes one if the shared library is directly or
indirectly dlopen()ed during the execution of the program, which could
have either kept references to the old environ or could change it in
some other thread. This has been observed for example on systems using
Samba NSS modules.
To avoid any other possible fallout, the constructor is split into a
new static library that needs to be linked explicitly into programs
using setproctitle(). As an additional safety measure the pkg-config
linker flags will mark the program as not allowing to be dlopen()ed
so that we avoid the problem described above.

Force setproctitle() into .init_array section
The GNU .init_array support is an extension over the standard System V
ABI .init_array support, which passes the main() arguments to the init
function.
This support comes in three parts. First the dynamic linker (from glibc)
needs to support it. Then function pointers need to be placed in the
section, for example by using __attribute__((constructor)), that the
compiler (gcc or clang for example) might place in section .ctors and
the linker (from binutils) will move to .init_array on the output
object, or by placing them directly into .init_array by the compiler
when compiling. If this does not happen and the function pointers end
up in .ctors, then they will not get passed the main() arguments, which
we do really need in this case.
But this relies on recent binutils or gcc having native .init_array
support, and not having it disabled through --disable-initfini-array.
To guarantee we get the correct behaviour, let's just place the function
pointer in the .init_array section directly, so we only require a recent
enough glibc.

build: Set default compiler variables from configure
This centralizes the setting so there's no duplication anymore,
makes sure the user supplied variables are never overridden, and
are only set when using gcc.

build: Set runtimelibdir to libdir

Regression introduced in commit 901ed630fc64fca828e031bc8fa6780db9f05db1.
