PowerPC PIC vs. DLL TLS issues

1) GOT entries generated for any of the GOT TLS relocations don't need dynamic relocations for locally defined symbols in PIEs. In the case of a tls_index doubleword, the dtpmod entry is known to be 1, and the dtprel entry is also known at link time and relative. Similarly, dtprel and tprel words are known at link time and relative. (GOT entries for other than TLS symbols are not relative and thus need dynamic relocations in PIEs.) 2) Local dynamic TLS code is really only meant for accesses local to the current binary. There was a cheapskate test for this before using the common tlsld_got slot, but the test wasn't exactly correct and might confuse anyone looking at the code. The proper test, SYMBOL_REFERENCES_LOCAL isn't so expensive that it should be avoided. 3) The same cheap test for local syms when optimising TLS sequences should be SYMBOL_REFERENCES_LOCAL too. bfd/ * elf64-ppc.c (ppc64_elf_check_relocs): Move initialisation of vars.
