Revert "Merge pull request #86954 from lovesegfault/binutils-2.34"

Pythons find_library is broken with binutils 2.34, and numpy could not import libraries because of not properly aligned ELF's.

This is the second time binutils 2.34 got reverted. Next time, we should have a dedicated Hydra job for it.

This reverts commit 629fa8a2d459449eeb3f7c911b765e58ac830254, reversing
changes made to 4ddd080d1978b821391ad099806c18ac6a654e41.

+Subject: [PATCH] x86: Properly add X86_ISA_1_NEEDED property
+
+Existing properties may be removed during property merging.  We avoid
+adding X86_ISA_1_NEEDED property only if existing properties won't be
+removed.
+
+bfd/
+
+	PR ld/23428
+	* elfxx-x86.c (_bfd_x86_elf_link_setup_gnu_properties): Don't
+	add X86_ISA_1_NEEDED property only if existing properties won't
+	be removed.
+
+ld/
+
+	PR ld/23428
+	* testsuite/ld-elf/dummy.s: New file.
+	* testsuite/ld-elf/linux-x86.S: Add X86_FEATURE_1_AND property.
+	* testsuite/ld-elf/linux-x86.exp: Add dummy.s to pr23428.
+
