-B is already documented in "Options for Directory Search": `-BPREFIX' This option specifies where to find the executables, libraries, include files, and data files of the compiler itself. The compiler driver program runs one or more of the subprograms `cpp', `cc1', `as' and `ld'. It tries PREFIX as a prefix for each program it tries to run, both with and without `MACHINE/VERSION/' (*note Target Options::). -- Eric Botcazou
