When I refactored the filesystem_error code I changed it to only use the
constructor parameter in the what() string, instead of the string
returned by system_error::what(). That meant it no longer included the
description of the error_code that system_error adds. This restores the
previous behaivour, as encouraged by the standard ("Implementations
should include the system_error::what() string and the pathnames of
path1 and path2 in the native format in the returned string").

To fix this we need to make the branch islands (or code) visible between

The new gt-rs6000-logue.h is common to all sub-targets in the port, so
it needs to be added for them.

It seems better to place the common target_gtfiles in the powerpc*-*-*

less likely that a sub-target would be overlooked in any future file
introductions.

and add them together.

We only apply it to 64-bit mode (DI) when implementing maddld.  However, if we
can guarantee that the result of the maddld operation will be limited to 32-bit
