Given your values for MCS and BOOTSTRAP_MCS, BOOTSTRAP_PROFILE is
irrelevant.  Also, shouldn't MCS also be 'gmcs'?

Hmm, depending on whether you want to sign the assemblies during the
build, there are a couple of options:

* If you don't need to sign the assemblies or can tolerate a custom
  separate signing step, you can use the following in profile/unity.make:

    NO_SIGN_ASSEMBLY = 1

* If you _do_ want to sign the assemblies during the build, and reuse
  the existing facilities: well, unfortunately, library.make isn't too
  helpful.

    ifdef NO_SIGN_ASSEMBLY
    SN = :
    else
    sn = $(topdir)/class/lib/net_1_1_bootstrap/sn.exe
    SN = $(Q) MONO_PATH="$(topdir)/class/lib/net_1_1_bootstrap$(PLATFORM_PATH_SEPARATOR)$$MONO_PATH" $(RUNTIME) $(RUNTIME_FLAGS) $(sn)
    SNFLAGS = -q -R
    endif

  You could surround the 'else' part of a that stanza in a 'ifndef
  SN'/'endif' (that change come pre-approved -- please go ahead and
  commit if it helps, and doesn't break anything else), and just set

    SN = sn

  in your profile/unity.make.
