tst-tlsopt-powerpc as a shared lib
This makes the __tls_get_addr_opt test run as a shared library, and so actually test that DTPMOD64/DTPREL64 pairs are processed by ld.so to support the __tls_get_adfr_opt call stub fast return. After a 2017-01-24 patch (binutils f0158f4416) ld.bfd no longer emitted unnecessary dynamic relocations against local thread variables, instead setting up the __tls_index GOT entries for the call stub fast return. This meant tst-tlsopt-powerpc passed but did not check ld.so relocation support. After a 2017-07-16 patch (binutils 676ee2b5fa) ld.bfd no longer set up the __tls_index GOT entries for the call stub fast return, and tst-tlsopt-powerpc failed. Compiling mod-tlsopt-powerpc.c with -DSHARED exposed a bug in powerpc64/tls-macros.h, which defines a __TLS_GET_ADDR macro that clashes with one defined in dl-tls.h. The tls-macros.h version is only used in that file, so delete it and expand. * sysdeps/powerpc/mod-tlsopt-powerpc.c: Extract from tst-tlsopt-powerpc.c with function name change and no test harness. * sysdeps/powerpc/tst-tlsopt-powerpc.c: Remove body of test. Call tls_get_addr_opt_test. * sysdeps/powerpc/Makefile (LDFLAGS-tst-tlsopt-powerpc): Don't define. (modules-names): Add mod-tlsopt-powerpc. (mod-tlsopt-powerpc.so-no-z-defs): Define. (tst-tlsopt-powerpc): Depend on .so. * sysdeps/powerpc/powerpc64/tls-macros.h (__TLS_GET_ADDR): Don't define. Expand use in TLS_GD and TLS_LD.
