When trying to bootstrap mainline on Solaris 10/x86 with the native
assembler, building libffi fails:

I had already noticed this on 20051006, but hadn't reported it yet since
the Solaris 10/x86 native as doesn't work due to still unfixed PR
target/23359.
The first part of the problem might perhaps be worked around by manual
calculations as in src/mips/ffitarget.h, but I don't know a good solution
for the second problem.
The bug was introduced by this patch:
2005-08-11 Jakub Jelinek <[EMAIL PROTECTED]>
* configure.ac (HAVE_HIDDEN_VISIBILITY_ATTRIBUTE): New test.
(AH_BOTTOM): Add FFI_HIDDEN definition.
* configure: Rebuilt.
* fficonfig.h.in: Rebuilt.
* src/powerpc/ffi.c (hidden): Remove.
(ffi_closure_LINUX64, ffi_prep_args64, ffi_call_LINUX64,
ffi_closure_helper_LINUX64): Use FFI_HIDDEN instead of hidden.
* src/powerpc/linux64_closure.S (ffi_closure_LINUX64,
.ffi_closure_LINUX64): Use FFI_HIDDEN instead of .hidden.
* src/x86/ffi.c (ffi_closure_SYSV, ffi_closure_raw_SYSV): Remove,
add FFI_HIDDEN to its prototype.
(ffi_closure_SYSV_inner): New.
* src/x86/sysv.S (ffi_closure_SYSV, ffi_closure_raw_SYSV): New.
This is a regression from at least 3.4 where it was possible to bootstrap
on Solaris 10/x86 with the native assembler. I don't know for sure about
4.0, though.
