Buidling profiled fails

[Austin Seipp]

Well, depending on ./configure is reasonable, but I'm not sure how to
easily make it work around these checks just for the 'show' target.

Hm, what platform is this, Win64? (I need to get a win64 test env up.)
You might possibly have an out of date mk/build.mk file, but if this
is a recent checkout then I doubt it. Otherwise there might be a
glitch in the build system that things you can support dynamic ghc,
but not shared libraries.

You should be able to turn this off in the mean time. You can put:

DYNAMIC_BY_DEFAULT=NO
DYNAMIC_GHC_PROGRAMS=NO

in mk/build.mk, anywhere above this line:

------
GhcLibWays = $(if $(filter $(DYNAMIC_GHC_PROGRAMS),YES),v dyn,v)
------

I really need to double back on and look over all the shared library
stuff this week.
