Fix PR12763, .tbss mishandling

[Alan Modra]

This fixes some fallout from my previous PR12763 patch.
hppa64-linux  +ERROR: /src/binutils-current/ld/testsuite/ld-elf/tdata3.s: assembly failed
The tdata3 test uses .tbss as well as .tdata.

ld/testsuite/
	* ld-elf/binutils.exp: Don't run tdata3 for hppa64.
