[PATCH v3 2/2] newlib/.../getreent.c: Do not define if __DYNAMIC_REENT__ is enabled

[Joel Sherrill]

RTEMS provides the option to have a global or per-thread reentrancy
as part of application configuration. As part of this, RTEMS provides
the implementation of __getreent() as appropriate. Allow the target
to determine if this method is present in libc.a.
