posix: Fix internal p{read,write} plt usage
This patch adds internal alias for __pread, __pread64, and __pwrite following the already in place one for __pwrite64. This is not used in any implementation but on microblaze on preadv/pwritev fallback (since it does not define __ASSUME_PREADV). In fact it was signaled by commit c35db50ff5 which update the expected localptl.data for the architecture based on resulted value. This patch updates the plt for microblaze now that p{read,write}{64} are correctly routed to use internal alias. Checked on x86_64-linux-gnu and a build for all supported architectures (no all variants although). * include/unistd.h (__pread): Add libc_hidden_proto. (__pread64): Likewise. (__pwrite): Likewise. * sysdeps/unix/sysv/linux/microblaze/localplt.data [libc.so] (__pread64): Remove. * sysdeps/unix/sysv/linux/pread.c (__pread64): Add libc_hidden_weak. * sysdeps/unix/sysv/linux/pread64.c (__pread64): Likewise. * sysdeps/unix/sysv/linux/pwrite.c (__pwrite): Likewise.
