ld: testsuite: Fix ld-elfvers tests on Solaris

All ld-elfvers tests FAIL on Solaris/SPARC, always with the same failure
mode:

FAIL: vers1

./ld-new: _etext: undefined version: vers1.so
./ld-new: _end: undefined version: vers1.so
./ld-new: _edata: undefined version: vers1.so
./ld-new: failed to set dynamic section sizes: bad value

This is due to the use of --no-undefined-version, the error being
emitted by bfd/elflink.c (bfd_elf_size_dynamic_sections).  The affected
symbols are mandated by the Solaris ABI in versioned shared objects and
are generated by ld/emultempl/solaris2.em
(elf_solaris2_before_allocation).  The check in
bfd_elf_size_dynamic_sections fails since for the base version (vers1.so),
both symver and script are 0:

vers1.so	pattern = "_etext", literal = 1, symver = 0, script = 0, mask = 1

Given that those symbols are generated internally by ld, it seems
sensible to set script = 1 for them.

This patch does just that, at the same time enabling the tests for
Solaris/x86.  Not doing this before looks like an oversight: there's no
difference between SPARC and x86 in this regard.

This introduces one failure on Solaris/amd64 (vers26b3), which I'll
address in a followup.

Tested no {sparc,sparcv9}-sun-solaris2.11, {i386,amd64}-pc-solaris2.11,
and {x86_64,i686}-pc-linux-gnu.

	ld:
	* emultempl/solaris2.em (elf_solaris2_before_allocation): Mark
	global symbols as generated by linker script.
	* testsuite/ld-elfvers/vers.exp: Enable on *-*-solaris2* rather
	than sparc*-*-solaris2* only.
