Add -Av9 to AFLAGS_PIC and AFLAGS_PIE in the ld test suite on SPARC.
Fixes the following ld test failures on sparcv9-linux-gnu:

FAIL: Build pr23162a
FAIL: Build pr23162b
FAIL: Build pr23161a
FAIL: Build pr23161b
FAIL: Build pr22263-1

due to:

tmpdir/pr22263-1a.s:26: Error: Architecture mismatch on "return %i7+8".
tmpdir/pr22263-1a.s:26: (Requires v9|v9a|v9b|v9c|v9d|v9e|v9v|v9m|m8;
requested architecture is sparclite.)

which happens when gcc generates v9 code by default.

This extends a similar fix made for Solaris/SPARC recently.
