There are some dependencies on binutils and gas in the test suite:

TEST_READELF = $(top_builddir)/../binutils/readelf
TEST_OBJDUMP = $(top_builddir)/../binutils/objdump
TEST_CXXFILT = $(top_builddir)/../binutils/cxxfilt
TEST_STRIP = $(top_builddir)/../binutils/strip-new
TEST_AR = $(top_builddir)/../binutils/ar
TEST_NM = $(top_builddir)/../binutils/nm-new
TEST_AS = $(top_builddir)/../gas/as-new

But those are only for a few specific tests and can probably be worked
around fairly easily. There's nothing in gold itself that depends on
binutils or BFD.
