Have I ever said how much I hate triplets?
Here's an updated version, plus some updates to install.texi to avoid
references to the obsolete ports.
OK?
R.
* doc/install.texi: Avoid references to obsolete ARM ports.
* config.gcc (obsolete): Add all ARM targets using the FPA.
(with_fpu): Obsolete selection of the FPA or Maverick on ARM.
web:
* changes.html: Describe obsoletion of FPA and Maverick on ARM.

+ <li>Support on ARM for the legacy floating-point accelerator (FPA) and
