scfi testsuite failure for Solaris2 build

[Jan Beulich]

Indu,

since Solaris2 has some special treatment, I'm routinely building
binutils for this target every once in a while. What I'm observing is

Executing on host: sh -c {../as-new  --x32 --scfi=experimental /home/jbeulich/cpp/binutils/master-git/2024-02-02/gas/testsuite/gas/scfi/x86_64/scfi-unsupported-1.s 2>&1}  /dev/null dump.out (timeout = 300)
spawn [open ...]
Assembler messages:
Fatal error: no compiled in support for 32bit x86_64
regexp_diff match failure
regexp "^Fatal error: SCFI is not supported for this ABI$"
line   "Fatal error: no compiled in support for 32bit x86_64"
FAIL: x86_64 scfi-unsupported-1

I expect this may affect more than just Solaris2; the testcase will
need adjustment or suitably qualifying.
