b7c801cac8 Two fixes. Better PLT pruning (don't emit PLTs for local functions). 
If emitting a reloc against a readonly section in a shared image,
cause TEXTREL to be set.

time to look at the gcc 4.5 codegen issues we should at least have a usable
-current for vax.

3fd38f84eb If we are asked to step on ptid(-1,0,0), then step on our inferior_thread 
instead, which is the main thread instead of the currently executing thread
which is not what we want, since we've been running and nother thread might
have just started.

f89a1d6f2b NetBSD fixes: 
1. thread_self() returns a pointer, not an unsigned integer
2. Add NetBSD to Apple and FreeBSD defines
3. Add _NETBSD_SOURCE where needed
4. Add an extra define BEGIN_PROTECTV for void functions to avoid return
   free(); where free is void.
5. Avoid weak symbol hacks to determine if we are threaded or not. We
   have a threaded copy of the library, why bother?
6. change __attribute -> __attribute__ since the former is not covered by
   our cdefs.h

d0800ba09f add preliminary build glue for mudflap; only the shared libraries work, 
the static ones will need us to add __real_foo aliases for a bunch of
functions in libc.

9b33eb8aa1 Undo previous, it was wrong: 
The problem has to do with the threaded initialization.
After we take the first breakpoint and we enter single step mode,
we set trap_expected = 1 in the thread_info structure for main <pid,0,0>.
After the threads initialize, the main thread becomes <pid,1,0>, and so
we get a new thread_info struct with trap_expected = 0, and so we break.

b3ed3f9f74 The default configuration for TLS support is supposed to use Sun 
as, but we use GNU as.  So in this case it generates wrong
relocations in non-PIC mode.

This change fixes lib/libc/tls/t_tls_dynamic test failure on 32-bit
sparc as described in PR toolchain/45985.

Approved by releng.
