Currently, the documentation for --with-multilib-list in gcc/doc/install.texi only mentions sh*-*-* and x86-64-*-linux* targets. However, arm*-*-* targets also support this option. This patch adds documention for the meaning of this option for arm*-*-* targets.

ChangeLog entry is as follows:


*** gcc/ChangeLog ***

2015-12-09  Thomas Preud'homme  <thomas.preudhomme@arm.com>

        * doc/install.texi (--with-multilib-list): Describe the meaning of the
        option for arm*-*-* targets.




PDF builds fine out of the updated file and look as expected.

Is this ok for trunk?

Best regards,

Thomas

Ok (since I don't think I saw a response from the ARM maintainers).

(The list of options for -mfpu= is a bit inconsistent with the other
cases, in that it has -mfpu= only in the first case, but I guess this
is fine if you want to keep it that way.)
