Joseph Huber 8e43acbfed [libc] Only add '-fno-builtin-*' on the entrypoints that use them (#100481) ...

Summary:
The GPU build needs to be able to inline stuff in LTO. Builtin
transformations cause problems on the functions that the optimizer does
heavy libcall recognition on. Previously we moved to using
`-fno-builtin-*` to allow us to only disable the problematic ones.
However, this still didn't allow inlining because each function had the
attribute that told the inliner not to inlining a nobuiltin function
into a non-nobuiltin function

This patch fixes that by only applying these attributes to the
entrypoints that define them. That is enough to prevent recursive calls
within the definitoins themselves.
