For some mind-boogling reasons, GCC 5.4 believes that a weak reference
cannot alias with an extern. While this is clearly bogus, avoid yet
another alias handling bug and use strong aliases. It's actually
slightly simpler, too.

joerg | Fun fact of the weak: a weak reference doesn't have visibility attached.
As such, reorganize the start/end references to use a weak reference
only, if we use it to remove size knowledge. Otherwise use weak
external declarations.

joerg | Make older GCC and Clang happy and use weak references to the elements,
not declared as arrays.

joerg | PR toolchain/51121:
__CTOR_LIST__ and __CTOR_LIST_END__ are logically the same object, but
due to the start marker, the former has to be declared as array of fixed
size. Newer GCC versions take the liberty of exploiting the UB of
accessing global objects past the end to unconditionally load zero
values in that case. Two fixes are possible:
(1) Pruning via inline assembler as done by GCC's own CRT copy.
(2) Pruning via weak references as done for linker sets.
Since the second part is known and required to work anyway, prefer this
approach. In theory, the labels could be replaced completely, except
that GNU as doesn't provide start/end symbols for sections containing
dots.

Also make sure the __CTOR_LIST__ is just aligned to a pointer boundary.
By default, mips N32 will aligned to a 64-bit boundary not 32-bit
which causes an extra NULL entry to be added.
Fix "segfault on exit" several people have noticed on mips N32,
caused by a jr to a NULL address.

Create references as absolute pointers internally for .cfi*.
Do not warn for anonymous relocations in read-only .eh_frame,
they will be turned into relative entries afterwards.
A const declaration with explicit section attribute should create a
read-only section, whether it is initialized or not.
Use read-only .eh_frame.
Detect advance_loc support with readelf, not objdump. The latter is
broken in some situations before binutils 2.28.
.eh_frame should be read-only on MIPS too.
Build PIC libs on MIPS and PPC64. While the normal calling convention is
position-independent, real PIC defaults to Global Dynamic as TLS model,
while non-PIC and PIE code can use more restrictive models like Initial
Exec. This is most visible with the thread_local destructor code now
using TLS in libc as it would be clobbered by any other shared library
with TLS due to static offset assignment by ld.
Fix encoding of LSDA entries. .eh_frame references in non-PIC mode can
use plain pointers. For PIC, any references to global objects must be
indirect, but the .eh_frame entries themselve should be pcrel.
One more missing check for DECL_INITIAL being non-NULL.
TLS relocations for PIE and non-PIE main executable work the same, so
apply the same relaxation rules and the same static binding rules.
