Remove configure test for ARM TLS descriptors support.
GCC 4.7 added support for ARM TLS descriptors. The binutils support is present in binutils 2.22. Thus, this patch removes the associated configure test as obsolete (leaving Makefile conditionals, as NaCl sets have-arm-tls-desc = no in its sysdeps fragment). Tested for ARM that installed shared libraries are unchanged by the patch. * sysdeps/arm/configure.ac (libc_cv_arm_tls_desc): Remove configure test. * sysdeps/arm/configure: Regenerated. * sysdeps/arm/Makefile [!have-arm-tls-desc] (have-arm-tls-desc): Define variable if not already defined.
