build: replace weak symbols with a static library
Weak symbols were a nice idea, but they turned out not to be a good one.
Toolchain support is just too sparse, in particular llvm-gcc is totally
broken.
This patch uses a surprisingly low-tech approach: a static library.
Symbols in a static library are always overridden by symbols in an
object file. Furthermore, if you place each function in a separate
source file, object files for unused functions will not be taken in.
This means that each function can use all the dependencies that it needs
(especially QAPI stuff such as error_setg).
Thus, all stubs are placed in separate object files and put together in
a static library. The library then is linked to all programs.

tci: fix build breakage for target MIPS
commit 5f7319cd introduced GETPC() usage for MIPS, which is currently
not defined when building with --enable-tcg-interpreter. Add MIPS to
the list of targets we selectively define GETPC() for.

tci: Fix build breakage (unresolved symbol tcg_out_tb_finalize)
Commit 32761257c0b9fa7ee04d2871a6e48a41f119c469 enabled
qemu_ld/st optimization unconditionally for some hosts.
The TCG interpreter still does not support this kind of
optimization. Therefore builds with TCI fail with an
unresolved symbol tcg_out_tb_finalize. This is fixed here.
