I'll preface this with a comment that I know very little about the
cross-lfs book, or cross building in general. However:

This is an error that a header file generated on its own, with an:
#error "TLS support is required"

No, you're not even getting to the point where the linker is running, so
crt1.o has nothing to do with it. I'll download that glibc snapshot and
see if I can figure out why this #error line is getting generated.
OK, if you look at lines 58 through 60 in nptl/sysdeps/sparc/tls.h,
you'll see this:
# error "TLS support is required."

output, I'd bet that it's because of this:
checking for sparc64 TLS support... no
