What is the recommended order of building gcc, gmp, mpfr?

I notice that now gcc depends on gmp and mpfr to build.

I believe the gmp recommends using gcc to build (although
it may build with other compilers).

What is the recommended order of building gcc, gmp, mpfr?
I can think of two options:

Option A. Use the bootstrap compiler to first build gmp and mpfr,
then build gcc.

Option B. Build gcc without gmp and mpfr. Then use it to
build gmp and mpfr. Now rebuild gcc using gmp and mpfr.

Are there other options? What is recommended?
