Add hidden __tls_get_addr/___tls_get_addr alias
__tls_get_addr/___tls_get_addr is always defined in ld.so. There is no need to call them via PLT inside ld.so. This patch adds the hidden __tls_get_addr/___tls_get_addr aliases and calls them directly from _dl_tlsdesc_dynamic. There is no need to set up the EBX register in i386 _dl_tlsdesc_dynamic when calling the hidden ___tls_get_addr. * elf/dl-tls.c (__tls_get_addr): Provide the hidden definition if not defined. * sysdeps/i386/dl-tls.h (___tls_get_addr): Provide the hidden definition. * sysdeps/i386/dl-tlsdesc.S (_dl_tlsdesc_dynamic): Call the hidden ___tls_get_addr. * sysdeps/x86_64/dl-tlsdesc.S (_dl_tlsdesc_dynamic): Call the hidden __tls_get_addr. * sysdeps/generic/localplt.data (__tls_get_addr): Removed. * sysdeps/unix/sysv/linux/i386/localplt.data (___tls_get_addr): Likewise.
