ghc-7.8-rc1/HEAD: --enable-unregisterised fails to build and run with threaded RTS, profiling mode

Steps to reproduce:

0. Pick any platform. I've performed it on amd64, but seen real failures on unreg arches: ia64, ppc64
1. pull sources
2. ./boot
3. ./configure --enable-unregisterised
# right, no build.mk
4. make

Here we see 2 kinds of bugs at once:

1. threaded RTS misses -DNOSMP define. Looks like ghc always needs

to carry that define (what is the mechanism for it BTW?), it

doesn't:

  HC [stage 1] compiler/stage2/build/ExtsCompat46.o

In file included from /home/slyfox/dev/git/ghc/includes/Stg.h:232:0:
    0,
                     from /tmp/ghc6527_0/ghc6527_2.hc:3:

/home/slyfox/dev/git/ghc/includes/stg/Regs.h:443:2:
     error: #error BaseReg must be in a register for THREADED_RTS
     #error BaseReg must be in a register for THREADED_RTS
      ^

The implicit declarations are scary as well:

/tmp/ghc1420_0/ghc1420_2.hc: In function 'c7WZ_entry':

/tmp/ghc1420_0/ghc1420_2.hc:43:1:
     warning: implicit declaration of function 'hs_bswap64' [-Wimplicit-function-declaration]
     _c7X5 = hs_bswap64(*((P_)(R1.w+7)));
     ^

I naively tried naive approach:

mk/config.mk.in:

+# Unregisterised build calls c compiler for every
+# .hs file. thus pass it everywhere.
+ifneq "$(GhcWithSMP)" "YES"
+SRC_HC_OPTS += -optc-DNOSMP
+endif

but got stage2, which always SIGSEGVs. Thus it's either incorrect fix or UNREG is broken.

1. profiling builds (all files with -prof) miss enterFunCCS declaration:

/tmp/ghc7183_0/ghc7183_1.p_hc: In function 's6Y_entry':

/tmp/ghc7183_0/ghc7183_1.p_hc:79:40:
     error: 'enterFunCCS' undeclared (first use in this function)
     ghcFunPtr = ((void (*)(void *, void *))enterFunCCS);
                                            ^
