Since 20220209, two tests FAIL on 32-bit Solaris/x86:
+FAIL: g++.target/i386/pr35513-1.C -std=gnu++14 execution test
+FAIL: g++.target/i386/pr35513-1.C -std=gnu++17 execution test
+FAIL: g++.target/i386/pr35513-1.C -std=gnu++20 execution test
+FAIL: g++.target/i386/pr35513-1.C -std=gnu++98 execution test
+FAIL: g++.target/i386/pr35513-2.C -std=gnu++14 execution test
+FAIL: g++.target/i386/pr35513-2.C -std=gnu++17 execution test

+FAIL: g++.target/i386/pr35513-2.C -std=gnu++98 execution test
The tests SEGV like this:

x86: Update PR 35513 tests
1. Require linker with GNU_PROPERTY_1_NEEDED support for PR 35513
run-time tests.
[...]
PR testsuite/104481
* g++.target/i386/pr35513-1.C: Require property_1_needed target.
* g++.target/i386/pr35513-2.C: Likewise.
[...]
* lib/target-supports.exp (check_compile): Support assembly code.
(check_effective_target_property_1_needed): New proc.
I honestly don't see how check_effective_target_property_1_needed does test for
linker GNU_PROPERTY_1_NEEDED support, which Solaris ld certainly lacks, thus
the tests shouldn't run in the first place.
