c22845744c
This patch consolidates all the non cancellable open calls to use
the __open_nocancel identifier. For non cancellable targets it will
be just a macro to call the default respective symbol while on Linux
will be a internal one.
To be consistent with the following non cancellable openat call, a
new __open64_nocancel is also added (although not currently used).
Checked on x86_64-linux-gnu, x86_64-linux-gnu-x32, and i686-linux-gnu.
