[PATCH] sparc64: relax tls linking test

- Subject: [PATCH] sparc64: relax tls linking test
The TLS test attempts to link an assembly program, but this implicitly
pulls in start objects. This obviously causes problems when attempting
to cross-compile glibc for the first time since glibc itself provides
these start files. So tweak the test to skip these bits which are
irrelevant to the test at hand.

* sysdeps/sparc/sparc64/elf/configure.in (libc_cv_sparc64_tls): Add
$LDFLAGS and -nostdlib -nostartfiles to linking step. Change main
to _start.
* sysdeps/sparc/sparc64/elf/configure: Regenerate.
