Heh.

For now, I added these flags to EXTRA_CC_OPTS in mk/build.mk.  It
seems to work.  Meanwhile --

I wonder if it matters whether PLATFORM_CC_OPTS is set to -static in
mk/bootstrap.mk?  The comments there say that the flags "should match
the list in machdepCCOpts in ghc/compiler/DriverFlags.hs", and
DriverFlags.hs does set -static for alpha.

(By the way, are *_hsc.[hc] files considered part of the ".hc
distribution"?  I needed them for compiling, say, Directory.hc.)

Anyway, the current hurdle is that
        ghc/lib/std/PrelInt.hc doesn't compile
because int64ToIntegerzh_fast is not declared
because ghc/includes/PrimOps.h did not declare it
because SUPPORT_LONG_LONGS is not defined in ghc/includes/StgTypes.h
because SUPPORT_LONG_LONGS is defined in ghc/includes/StgTypes.h
        if and only if HAVE_LONG_LONG && SIZEOF_VOID_P < 8,
        and SIZEOF_VOID_P is 8.

I'm not sure what the right fix is here.  Why does StgTypes.h not
define SUPPORT_LONG_LONGS if SIZEOF_VOID_P >=3D 8, anyway?
