Nonsense:
https://ftp.gnu.org/gnu/binutils/binutils-2.35.1.tar.gz
https://ftp.gnu.org/gnu/binutils/binutils-2.35.1.tar.bz2

Yes, but you could try looking at the script and seeing what is not
being expanded, and find out why.

I just did that, and it's because the Makefile uses GNU make syntax,
and the default Make on FreBSD is classic UNIX Make. Use gmake
instead.

I've just successfully built binutils-2.35.1.tar.bz2 (downloaded from
the GNU FTP site that you claim doesn't have it) on gcc303. All you
need to do is run gmake instead of make (or alias make=gmake).

Are you sure that's not also the problem you had trying to build GCC?
GCC requires GNU Make, so be sure to use gmake to build gcc.

I meant already installed, i.e. in /usr/local

It looks like it isn't there.
