This stores errno, the cancelation flags, and related bits for each thread
and is allocated by ld.so or libc.a. This is an ABI break from 5.9-stable!
Make libpthread dlopen'able by moving the cancelation wrappers into libc
and doing locking and fork/errno handling via callbacks that libpthread
registers when it first initializes. 'errno' *must* be declared via
<errno.h> now!
Clean up libpthread's symbol exports like libc.
On powerpc, offset the TIB/TCB/TLS data from the register per the ELF spec.
Testing by various, particularly sthen@ and patrick@

Stop generating _brk and _sbrk symbols: they've already been hidden.
Set the ELF symbol size on the syscall stubs.
Give the __{min,cur}brk symbols a size and type, and hide more jump labels.

Delete exect(2); it wasn't portable across archs and nothing used it.

invocations. This allows us to use the compiler builtin define __PIC__ to check
for PIC/PIEness rather than passing -DPIC. Simplifies PIE work a lot.
