Yes I'm sure about the binaries distributed by mingw.org

I used mingw build of gcc to build gcc.  Earlier builds of mingw gcc
(2.95.2 and earlier) were cross-compiled on linux I think.

Here is how gcc.exe and mingw32-gcc.exe come into the world
(from the Makefile):

# Install the driver program as $(target_noncanonical)-gcc, 
# $(target_noncanonical)-gcc-$(version)
# and also as either gcc (if native) or $(gcc_tooldir)/bin/gcc.
install-driver: installdirs xgcc$(exeext)
	-rm -f $(DESTDIR)$(bindir)/$(GCC_INSTALL_NAME)$(exeext)
	-$(INSTALL_PROGRAM) xgcc$(exeext) $(DESTDIR)$(bindir)/$(GCC_INSTALL_NAME)$(exeext)
	-rm -f $(DESTDIR)$(bindir)/$(target_noncanonical)-gcc-$(version)
	-( cd $(DESTDIR)$(bindir) && \
	   $(LN) $(GCC_INSTALL_NAME)$(exeext) $(target_noncanonical)-gcc-$(version) )
	-if [ -f gcc-cross$(exeext) ] ; then \
	  if [ -d $(DESTDIR)$(gcc_tooldir)/bin/. ] ; then \
	    rm -f $(DESTDIR)$(gcc_tooldir)/bin/gcc$(exeext); \
	    $(INSTALL_PROGRAM) gcc-cross$(exeext) $(DESTDIR)$(gcc_tooldir)/bin/gcc$(exeext); \
	  else true; fi; \
	else \
	  rm -f $(DESTDIR)$(bindir)/$(target_noncanonical)-gcc-tmp$(exeext); \
	  ( cd $(DESTDIR)$(bindir) && \
	    $(LN) $(GCC_INSTALL_NAME)$(exeext) $(target_noncanonical)-gcc-tmp$(exeext) && \
	    mv -f $(target_noncanonical)-gcc-tmp$(exeext) $(GCC_TARGET_INSTALL_NAME)$(exeext) ); \
	fi

in this case $(target_noncanonical) = "mingw32"
and $(LN) is effectively cp
