Subject: Fix "conflicting types for built-in function" warnings from nldbl-*.c
Building for powerpc32, and probably other systems using ldbl-opt
(i.e. supporting -mlong-double-64, now defaulting to
-mlong-double-128, where a previous version only supported
-mlong-double-64), produces many "conflicting types for built-in
function" warnings building the nldbl-*.c compatibility functions for
code using -mlong-double-64 (the code is using the type "double" in
defining the versions of the long double functions that just wrap the
functions for double).  This patch fixes this by using the appropriate
-fno-builtin-<function> option or options for each affected source
file, to disable the conflicting built-in declaration.

(There are still quite a few warnings left for powerpc32 after this
patch ... I hope the architecture maintainers will also look at them
for 2.17, and that they will look at cleaning up warnings for
powerpc64 as well.)
