ld: testsuite: Only xfail "shared (non PIC)" etc. on 64-bit Solaris
Once the ld-shared tests run on both Solaris/SPARC and x86, two tests
XPASS on 32-bit Solaris, both SPARC and x86 (pre-existing on SPARC,
newly revealed on x86):
XPASS: shared (non PIC)
XPASS: shared (PIC main, non PIC so)
Consequently, this patch restricts xfailing them to 64-bit Solaris.
There now remain 1 (32-bit) or 3 (64-bit) XFAILs. I've checked the
reasons and found all comments in shared.exp are wrong:
* The common one (SPARC and x86, 32 and 64-bit) is
XFAIL: shared (non PIC, load offset)
The error is always the same:
ld.so.1: shnp: fatal: tmpdir/shnp.so: unknown file type
Running shnp under truss reveals
26170: openat(AT_FDCWD, "tmpdir/shnp.so", O_RDONLY) = 3
26170: mmapobj(3, MMOBJ_INTERPRET, 0xFFFFFFFF7F5D0058, 0xFFFFFFFF7FFFE8A0, 0x00000000) Err#48 ENOTSUP
which can be traced in the mmapobj(2) implementation to the
requirement that a shared object's p_vaddr needs to be 0, which in
this test is intentionally not the case.
* The other two XFAIL's are 64-bit only and for another reason:
XFAIL: shared (non PIC)
XFAIL: shared (PIC main, non PIC so)
On sparcv9, shnp execution fails:
ld.so.1: shnp: fatal: relocation error: R_SPARC_H44: file tmpdir/shnp.so: symbol shlibvar2: value 0x3fffffffb9c does not fit
On amd64, shmpnp.so fails to link:
ld/tmpdir/ld/collect-ld: tmpdir/sh1np.o: relocation R_X86_64_32S against symbol `shlib_shlibvar1' can not be used when making a shared object; recompile with -fPIC
ld/tmpdir/ld/collect-ld: failed to set dynamic section sizes: bad value
In both cases, this happens with -z text, too, so the comments are
bogus. Instead, the issue that the code needs to be PIC.
So I'm updating the comments accordingly.
Tested on sparc{v9,}-sun-solaris2.11 and {amd64,i386}-pc-solaris2.11.

ld:
* testsuite/ld-shared/shared.exp (shared (non PIC)): Update
comment. xfail on 64-bit Solaris only.
(shared (PIC main, non PIC so)): Likewise.
(shared (non PIC, load offset)): Update comment.
