- References: <20170901180029.9527-1-hjl.tools@gmail.com>
Mark __ptsname_internal, __mktime_internal and __fopen_internal with
attribute_hidden to allow direct access to them within libc.so and
libc.a without using GOT nor PLT.
[BZ #18822]
* include/stdlib.h (__ptsname_internal): Add attribute_hidden.
* include/time.h (__mktime_internal): Likewise.
* libio/iolibio.h (__fopen_internal): Likewise.
