re PR libffi/26048 (libffi doesn't build on Solaris 10/x86 with native assembler)
PR libffi/26048 * configure.ac (HAVE_AS_X86_PCREL): New test. * configure: Regenerate. * fficonfig.h.in: Regenerate. * src/x86/sysv.S [!FFI_NO_RAW_API]: Precalculate RAW_CLOSURE_CIF_OFFSET, RAW_CLOSURE_FUN_OFFSET, RAW_CLOSURE_USER_DATA_OFFSET for the Solaris 10/x86 assembler. (.eh_frame): Only use SYMBOL-. iff HAVE_AS_X86_PCREL. * src/x86/unix64.S (.Lstore_table): Move to .text section. (.Lload_table): Likewise. (.eh_frame): Only use SYMBOL-. iff HAVE_AS_X86_PCREL.
