ld: Fix pr22269-1 on 32-bit Solaris/SPARC 

pr22269-1.s currently FAILs to assemble on 32-bit Solaris/SPARC:

ERROR:  -K PIC tmpdir/pr22269-1.s: assembly failed

I could trace this to the fact that gcc on sparc-sun-solaris2.* defaults
to --with-cpu=v9.  So the gcc -S step of compiling the testcase is run
with -mcpu=v9, while the manual invocation of as-new lacks the
corresponding -Av9, creating a mismatch.

Solaris seems to be the only affected target, otherwise only
64-bit-default configurations default to --with-cpu=v9 or
--with-cpu=ultrasparc: sparcv9-*-*, sparc64-*-*,
sparc64-*-freebsd*, ultrasparc-*-freebsd*, and sparc64-*-openbsd*.

This patch just adds -Av9 to AFLAGS_PIC in ld-elf/shared.exp.  It has a
precedent in ld-elfvers/vers.exp where -Av9a is added to as_options on
sparc-*-*.  It lets the test pass and causes no other changes in
sparc-sun-solaris2.11 test results.

	* testsuite/ld-elf/shared.exp: Add -Av9 to AFLAGS_PIC on sparc*-*-*.
