[Patch] *-*-solaris2.[56789] (cross) don't actually have strtold or strtof (3.4 and trunk)

[Brad Spencer]

Oops!  It seems way back on May 22, 2003, or thereabouts, I posted
some new Solaris cross configury that wasn't quite right.  It looks
like I presumed the strtof() and strtold() C99 functions were present
because they had already been in the '*' (all systems) section.  It
turns out that they're old available as of Solaris 10.

This didn't show up until I got some time to (finally) build
gcc-3.4.3 for Solaris, which now tries to use these functions if
available.  AFAIK, they weren't used in 3.4.2 or earlier.

Sun's online documentation seems to indicate the functions exist on
Solaris 10 but not Solaris 2.9.  The man pages first lists them in
Solaris 10:

http://docs.sun.com/app/docs/doc/816-5168/6mbb3hrqq?a=view

Attached is a patch against the 3.4.3 crossconfig.m4, presuming that
the triplet for Solaris 10 is *-*-Solaris2.10 :)

The same change needs to be applied to the 3.4 branch and mainline.
